This following thing seems cool. How does it work?

Loving this new feature. Seems fresh. Nice on @csallen + @channingallen.

Thanks! There's lots of improvement to come.

Am I right in thinking that "Posts" on your "Following Feed" aren't "Posts" on the "Forum". But any "Posts + Comments" on the "Forum" are seen on your "Following Feed". Guessing you've differentiated between "forum" posts and "feed" posts?

Yes, yes, and yes. Let's call them forum threads and feed posts.

But unblurring that line seems the challenge to me. Be nice to have clearly differentiated on the "Feed" between what is a "Tweet" and what is a regular "Forum Post / Comment"

Yep, I'll consider differentiating them visually. I suspect that it won't take too many months before the feed posts vastly outnumber forum threads in the feed. Any given person who uses both features is likely to make more posts than threads.

Also, if we could see our on "feed" posts it would be easier to follow what's going on. Work in progress i know

Yep that's coming, via your user profile. For now I just recommend just following yourself so you can at least see your own posts in the feed.
