When somebody asks a question which needs a picture illustration, there is an easy mechanism for SE to copy the picture to imgur when embedding it. Not so with videos; when a question, like this one is effectively a request to describe the objects shown in a clip, and the video clip goes dead, as...

A minute or so ago, I attempted to post a question. This resulted in a pop-up (well, "lightbox" div) being drawn on the screen, with the following text in it (my emphasis): Human Verification Are you a human being? We apologize for the confusion, but we can't quite tell if you're a per...

When I view on mobile I see two text sizes, with no apparent reason why. You can see some have been visited and some not, so I don't think this is a design choice. I checked other SE sites and it is the same. If I had my pick, I prefer the bigger text to be the default. I'm using a Samsung...

What can be done about moderators who delete reasonable comments and answers, simply because conflict with the moderator's personal prejudices?

Was the wheel invented before the wall? is trivially answerable by looking up the history of "Wheel" and "Wall" on Wikipedia. That is why I -- providing those links, plus a link to the "Wall of Jericho" -- asked the OP what remained unanswered. My understanding was that "claims" that are trivia...

This is prompted by the comments seen on this question (and this). Basically: are questions asked in the early days of this SE (e.g. this one) a good indication of what we deem on topic? Or has the community changed focus and we deem such questions off-topic? Or is the situation fuzzy and not...

SE is giving us pretty limited options for how the site is going to look going forward.

We know that on an idempptent semiring $R$, the natural order relation is defined as: for all $x, y\in R$, $x\leq y$ when $x+y=y$, which is clearly a partial order relation.

What community thinks about idea giving "bountied questions" more attention ? I almost never look on the tab "featured", I guess I am not alone. So I guess such questions deserve little attention. On the other hand if someone giving bounty, then (imho) it should be respected somehow, it is so...

A lot of the Winter Bash hats look really familiar to me! An example being "Glasses With A Number On Top": Are hats reused from previous Winter Bashes? If so, which hats and when were they reused?

I always look forward to Winter Bash. This year it feels really hard to get any hats. And because of this I kind of quit giving it much thought after a few days. That's a shame because it takes a lot of time to come up with all that stuff for us! Is it just me or are Winter Bash hats too hard ...

The Winter Bash hat rack shows which sites you've earned a hat on: What is the order of these sites? If you're on a site where you've earned the hat, that site comes first, but the order of the other sites seems random. It's not a chronological order, and it switches between sites: but sub...

NOT TRIVIAL By hat, I mean all items in the Winter Bash (hats, googles, etc). Why can't I wear more than one? I know it's a little awkward to wear two hats but why can't I wear a hat and a google at least?

Quote from this comment (posted by balpha ♦): ... While the publicly visible behavior is like you don't have hats (e.g. it's not visible on your avatar, you don't count towards the site leaderbords, etc.), the fact that you deserve the hat is recorded for all users, regardless of opt-out stat...

How do all of you make a gif knit with the winter bash knitting website? I saw a couple of gifs from this question here And I thought maybe I could make mine into one. But I'm not too sure how?

Why does viewing the Winter Bash hats of a user on a Meta Stack Overflow user profile page redirect the user to Stack Overflow's user activity page?

I thought that they represented the rank of the person by the number of hats they have collected. The numbers "jump" 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?

I can’t see the review or help icon in the top bar. All I see is hats and some other stuff: The help icon is typically missing for me when I unlock review. But it’s blocked by hats even on sites where I don’t have review unlocked. This is happening on my tiny phone in portrait (the only layo...

I got the hat "retro fan" and I got 2 reputation points. Once the hats are gone, do we lose the amount of reputation we get from them or do we keep it?

On the Winter Bash 2018 page I read that Winter Bash will end on January 2nd: the hats get put back in their boxes on January 2nd! Earlier years Winter Bash has ended on January 4th: the hats get put back in their boxes on January 4th! How is the end date for Winter Bash chosen?

On the blog we are told "that on January 2 all hats will be taken back to storage." Does that mean the Winter Bash includes the second or is the first the last day? Times help clear up ambiguity: does WB end on Jan 2 0000 UCT or Jan 3 0000 UCT?

The Winter Bash chatroom is not linked to a particular site, so there are no hats available for getting a star on New Year's Eve. In my opinion, it should be linked to this site (i.e., Meta Stack Exchange).

Tomorrow (January 2nd 2019) is the day that Winter Bash will be gone. So I am thinking: Will there be some sort of a final ranking page? It would be nice so I don't need to keep going to the Leaderboard every day to see my rank. If there isn't going to be anything like that, what should I do t...

I didn't know when Winter Bash would end, so when my hat disappeared, I thought that the site would be closed, too. But it was still open, so I could add a new animated knitting to my answer. Will it be available, so I can knit a winter knitting in summer?

hatdash.com was used for Arqade's Hat Dash. Currently, the site shows the SO contests page but does not redirect to it. Since past Winter Bash sites all redirect to the contests page, is there a particular reason why the Hat Dash site doesn't?

Up until 2016, there were polls asking if we wanted to participate in the annual Winter Bash Hat Festivals. Why haven't there polls the past couple of years? I realize the votes have been overwhelmingly in favor of hats, so they might seem pointless, but being pointless is not a reason for not ...

Despite the closing of the Winter Bash last week, there are still a few hats on the profile pictures of some users. Is it a bug?
