I agree with this. It seems to me that Facebook puts most focus on the feed and that's hard to compete with. Flipboard has a nice take on this - unfortunately, locked in an app instead of on the web.
You have done a great job with the rest, navigation, and image browsing. There were a few glitches, the user info box and posts in the feed with images in them could use some finish.
All in all, great job and I think I understand where you're going with this!
This was definitely a conflict I had. I wanted to focus completely on photos but most test users wanted to be able to see their stream and comment/like. This is the most volatile feature in Portrit and will most likely change in the future.
