/mlp/ has devolved even further into fetish general hell despite and even aided by the fact that season 5 is going strong. I predict this trend will continue until only fetish generals remain.
/i/ has had Shi-Painter return and die again in short succession, to be replaced by Tegaki which is GARBAGE.
/pol/ finally calmed down from the fucking disaster it was late last year and early this year, and it got flags, which basically means it's like a red board version of /int/ now.
/vg/ differs so much from general to general that the board's overall feeling is almost impossible to determine, so I'm gonna go with "hasn't changed much at all."
/gif/ seems to have calmed down with the rampant flagrant homosexuality and cuckolding it used to have, e.g. sissy, cheating, and BBC threads being ubiquitous and filled with some of the lowest quality posting this side of /b/, but it's definitely still present.
So statistically speaking, and speaking only from the boards that I use at least weekly, things are looking up for 4chan as a whole in my opinion.
