it seems to be people on, that sw thinks you want to interact with, perhaps it thinks they want to interact with you. another halfass job that kinda doesn't seem to work for most people, if I'm being overly honest. used to be they'd tell you about coming changes in posts that it wouldn't allow you to skip. now it seems they're more concerned about making sure you see their responses and corrections to people criticizing/speculating on how things are done/work.
