There's still no easy or consistent way to separate certain types of topics and discussions imo.

Even if people want to get deeper in to a discussion, seems like pure luck on if they catch your note that talks about that particular thing. I rarely make it through my entire feed of missed notes. Some days I miss most of it due to life.

There are several people who constantly post things I'm interested in. Often I completely miss those posts and discover them many days later when I might randomly check their profile.

All I'm saying is, might not be totally a "people problem". I for one am glad the overall sentiment is lots of GMs and clouds, but I also see where you're coming from.
