I have asked on meta.SO why Math.SE twitter account behaves rather differently from the accounts of other sites. Namely that the posts which get to network-wide hot questions list are not tweeted.
I have had a look at the twitter feed of Math.SE. Looking at the recent post, I only see questions with bounty.
According to this answer, the bot chooses which questions should be tweeted according to some kind of hotness score. The answer does not specifically mention bounties.
I would like to...
I was told that the probable reason might be this: "The twitter bots are apparently configurable per-site. Someone configured it not to tweet hot posts "
Could this really be the case? Who configures these things? (I suspect that moderators might have access to this, that's why I asked here. Originally I though that this is not Math.SE specific, which is why I asked on the main meta.)
@MartinSleziak They are probably incorrect. The bot tweets once every 3 hours, so it has 8 tweets per day. There are several categories of posts that are tweetable: bounties, unanswered, often viewed, hot on meta. Of these, bounties have the highest priority: every bountied post gets tweeted. And we do have a lot of bounties.
So the result is; the twitter bot builds a backlog of bountied posts waiting for their turn. E.g., this post waited 2 days for its turn. While this backlog exists, no other category can be tweeted.
It's all just my observations of what the bot does. I don't know if its algorithm is documented. By the way, it's meta.SE you're referring to, meta.SO is at meta.stackoverflow.com
I suppose not. Twitter bots are all the same. Stack Overflow doesn't have one because the algorithm doesn't fit their level of activity. Math is at the point where the algorithm fits poorly.
Also, nobody at SE deals with Twitter bots anymore; they found them pretty much useless after a while and stopped creating them for new sites, as not being worth the effort. Bots still work like forgotten soldiers of the robot army.
Maybe I overstated things: they still remember about the bots and decorate them with site's theme once the site graduates (recent example: Raspberry Pi). But it's true that they stopped making new ones, so for example Worldbuilding, which is getting its design soon, doesn't have a Twitter bot.
