I agree with a lot of what's already mentioned here. Some of these updates are great! The only thing I would have to complain about is showing "likes" and even "comments" on the wall. It looks cluttered already, and even though I only write positive comments about other people's comics, it's a little uncomfortable to see everything displayed on my own wall like that.
The Journal thing might be an interesting idea? Don't know, hadn't really thought about it until others mentioned it.
Other than that; great job! I like the profile wall filters a lot, as well as the activity page filters, awesome
