It's digital art, if you want to be more popular presentation helps out a million.
I'm saying this because I couldn't do anything more than view thumbnails of the pieces which I don't want to judge some one's work from.
I mean for videos you can use sites like VIMEO and youtube, and there are tons of hosting sites for images (tumblr, etc.) I mean even a blogspot would be better than just a rhizome profile.

5-7.50 a month isn't that expensive (and that's for a pretty large plan)

So many fake suicide videos, or archived suicide videos are played on chat roulette on a regular basis that it's hard to expect any real reaction from it's viewers.

I would suggest having some where else besides a rhizome profile to host your work.

I feel the idea you had that would be "too literal" would be far better, because it actually would have an illustrated critique. You would know directly what it's targeting. Logorama instead comes out sloppy, with an almost random selection of logos with their only relation being how they look and not what they stand for. Quickly it becomes a gimmicky tool that is only celebrating the visualization of logo's rather than contemplating or presenting these logos in any meaningful way.
