Oops, sorry about that! I guess this is how user feedback usually goes right? People not having a clue what they are talking about. :)

I didn't realize the arrow was an upvote button. Maybe just needs a different treatment to make the use more clear.

The "hide comments" link is kinda hard to find, and have to scroll to top to use it, which is awkward. If I use it, I can't look at the comments at all! Would be nice to have some way to see what the circle refers to while still reading the comments.

Rep system might work or job titles might work. Just some clear way to communicate experience level. Also, I'd use this in other ways, by looking for designers with less experience, and commenting on their uploads more than others. This appeals to me, because on sites like Dribbble, more experienced designers tend to get more comments. Would love to see that inverted.
