While I’m not against the change, I feel like it’s asking to fix symptoms of an illness and not the illness itself. When people are opening individual forums to read on already opened posts, it feels like this is unnecessary cumbersome—especially on mobile. Personally, I never do that. I use the activity feeds only, because I can see everything at a glance and I don’t have to explore individual forums one by one. And I make sure my activity feeds are very prominent on the site, so my users also go with them.
