Mostly I don’t. Questions die a natural death and people stop posting to them. It’s quite interesting when a new member finds an old question and responds and starts the discussion again.
I tend to unfollow when there is a lot of bickering on the thread or when I don’t find it interesting at all.
I rarely actually hit the unfollow button. I do it when I see a topic coming up as having activity that I realize I really don’t care about, which is rare. However I often effectively stop following them by ignoring the Activity For You link (I show 1724 new at the moment) because it’s so slow to load. I usually only go to threads via GA votes, or the Next / Newer / Older links at page bottom, unless I am procrastinating or remembering some specific thread I want to check.
I’ll sometimes unfollow when a topic is timely and is not something relevant any more, for example the Presidential election 2016. Maybe at the time it was interesting to me but now it’s old news.
Whenever some idiot ruins it by chasing their own agenda in babbling on sometimes against me personally, love the fact they must continue to post shite aimed at me & i’m not there :D
Almost daily I’d say.
Depends on the Q. if is just some, not very interesting, bit of fluff I delete it within hours. I’m an out with the old in with the new type. Lets move on already is my mantra!
