I got a secret hat "Chameleon hat".    I wonder what it is for.  I am confused between two possibilities:   Multiple Stack accounts Change in Display picture   What is it for exactly?

So far, I've unlocked one of the secret hats. I'm wondering what other secret hats are out there and how to earn them?

We just noticed on the Tavern on the Meta, that hats seem to have vanished on chat.  They also seem to be gone on regular chat, and I don't see the snowflake on Meta Stack Exchange some of the time (it's randomly appearing by the looks of things then vanishing).  I usually use Vivaldi, but the same issue on Firefox (I'm on 57 or thereabouts).  I suppose we can blame load, or hats..  or is it a hat hating grinch?      Totally glitched grinched I guess

I don't understand what the white circle with the cross is for. I can change its position by left mouse click in the 3D view. Why does it change its position and what it is for?

on Ask Different appears to have no name due to invisible Unicode characters:    he's the #2 user on the site:    Why is that allowed? I think it is confusing for users, e.g. when they will see at the bottom of an answer:    It's not clear who answered, not clear what the rep numbers and badges are related to, and not clear how you can @reply to that user in the comments!

The hats seem to be designed for passport-photo-like avatars. Perhaps it would be better if you could choose where exactly it fits?

Some hours ago I was awarded the Good Question badge on Meta Stack Overflow:   It's a silver badge, but I didn't receive the      earn a silver badge     Seems a bug, or is it because meta badges are ignored for hats?

I tried to write , but I couldn't find any simple explanation page to link to. I ended up garbling a home-spun description of my own with a not-terribly-helpful image from 2012.  This  puts it better than I can:     As a new user in 2015 can there please be more information about what is WinterBash. The link took me to a bunch of stick figures running around making (I think) numbers (I think its a countdown clock). It doesn't explain the event or even what a hat is. – Ian Miller Dec 4 at 2:58   All I found on Meta was dead links. For example,  was downvoted to -2 and answered with a link to an FAQ page that no longer exists.

I just received my first  Secret Hat, so I decided to start the traditional Secret Hats and how to get them spoiler question.    Note: Please edit the primary list of secret hats with definitive answers only. If you'd like to discuss the hats further and/or work towards identifying what their triggers are, please do so in chat as the comments here are not meant for extended conversations about them.

I've just earned the "Warm Welcome hat" and the red star on it looks like a communist symbol. I associate this symbol on this particular hat closely with many atrocities against my country: Poland, as well as Czechia, Hungary, Slovakia, Ukraine and many others from inside the Iron Curtain.    I hope I don't get banned by this. It's just… I was really shocked to see it this morning.     Disclaimer: text below was added by a moderator, not me  Can Stack Exchange be more mindful of the symbols used when it's just about fun?

Is this a StackExchange site? It looks and seems to function the exact same, but seems to have its own user system, and doesn't contain links to all of the other SE sites at the bottom like all the ones I've seen do.  If this is not an "official" SE site is it acceptable for third party sites to "copy" the look &amp; feel of SE to this extent or is this site in violation of something?

Previously, in order to explain the benefits of (certain limited kinds of) duplication on Stack Exchange sites, I've seen a blog.stackoverflow blogpost with the words "Dr. Strangedupe" in the title.  The post comes up in a search on the new blog, but       Can we please bring this post back? I'd love to link to it when , to reassure the questioner that there is value in not deleting their question because of search terms, but the blog post explained it a lot better than I could in a comment.

Continuing the tradition of asking for the meanings of .  Hats like  can be deciphered easily as related to . However, hats like  are difficult to .   bluefeet has already mentioned about the number-only hats .   Hence the question is: can we have a list of what inspired each of the (secret and non-secret) hats?

When I first signed up on a Stack Exchange site and got a profile image, it was this one (see my current user card I'm actually not sure what I look like any more):     Later, I got  and SEDE profiles, and my user image there was a different identicon. Because . I would have a picture of it, but that's the problem. ... Thanks to , I have a picture:     On those two sites, it changed from that purple one to this new one recently:   I don't know when the change happened exactly, but I KNOW I didn't change it (I don't know how to change it, otherwise I would have changed it to my main pink one).  Why did this change? Can I get my other icon back or will I be stuck with this new one?   Also, are the gravatars at Area 51 and SEDE securely generated?    After looking in my profile settings, I really confused (I am seeing my wrong avatar in more and more places since I first posted this.):        Seriously.......    What...?    (I'm using this , but be warned that they will try to IP block you after a certain number of requests to force you to pay... May look for a better alternative later.)

I thought that they represented the rank of the person by the number of hats they have collected. The numbers &quot;jump&quot; however, they do not follow an unbroken order:  There are also really big gaps:  What do these number mean? Are they supposed to be like this?

What exactly is a hat?  I have seen a lot of people arguing the significance of hats and the limited edition hats. I know the hats are sort of linked to the Winterbash stuff, but what exactly is a hat, what does it do, how do I get one?  Is there a full list of hats?

I really like the hats game. But I would love to keep the hats longer then only one winter. I want to leave them in my wardrobe during summer. Last year, I collected some cool hats, and I apparently lost them during summer.  Maybe we could make a system that allows hats to last for about 2 or 3 years, so we don't have to start over each winter. Or even specify per type of hat a number of years they last? Very very rare hats could last for ever.  I asked this, simply because I love hats! :D

I've just been awarded the  bage!  Whooo, go me (didn't even realise it existed)!  =D I'm curious to know which of my (all rather mundane) comments has brought for me such honour. I found , which suggests using .  However, that query shows that I have only 2 comments with a score of 5 or more and I can't see anything wrong with the query... Do I not deserve this shiny new badge?  :(
