user1987: Checking the revisions history in any of my questions, I noted that appears when my question was tweeted by @StackAnime, and two things called my atention:   

One of the question appears tweeted two days after I wrote my question,
but another 4 hours after.
One of the tweets shows exactly the title of my question, but another
tweet has "Can you answer this?" to the beginning.

All this makes me wonder if is someone who is tweeting the questions(I thought it was just a bot).  
So, if is a human, is more than one? this is gonna be forever or is just gonna be while Anime & Manga is in beta?
In any case, what's the criteria to tweet a question? or all the questions are gonna be tweeted sonner or later?

user63: The @StackAnime account is most definitely a bot. The specific inner workings of the bot has not been publicly disclosed.
According to this answer there is a "hotness" algorithm based on views over a certain period of time.  Which is likely to be similar to the algorithm that populates the recently active questions page. 
In the same answer, it's been noted that questions have to have a score of >= 1 in order to be tweeted. There seems to be another check to avoid tweeting questions that have close votes, unless there is an active a bounty on it.
