For example, this is my homepage right now: http://i.imgur.com/1GpyP.png
Much of the comments that show up are snippets of conversation between other people. Often along the lines of "Yes, I agree," or other dialogue that doesn't make any sense out of context.
I can go to each post and figure out what they're talking about, but digesting content is a lot more awkward now.
I added the filter bar back to the activity streams, but it no longer includes comments/likes. I was reconsidering the word "Posts". It includes image uploads, snippets, apps and scripts. I was thinking about changing it to "Projects" or something a little more descriptive.
