I can say that, at least for me, the timeline and lists load far slower than they used to, to the point I see spinners for each individual item in the trending topics list for a second or more before they finally load in. I don't remember the last time that happened to me pre-buyout.

There have never been more spam bots in the replies and the site and apps are getting stuck in weird cache loops for the first time that I can remember. It's obviously a very robustly built platform but to me, it seems like it's coasting and hoping that nothing too big breaks.
