I am just checking out Imgur and Reddit myself, and I find the whole thing to be a bit confusing to say the least. On Imgur it seems you can access a large audience in a brief amount of time, but anything you drop into that bucket drowns in an ocean of kitten gifs and memegenerator stuff.
Reddit, I thought it was broken at first. Page looks like something that should be left behind in the 90's. I couldn't see my own posts and nothing that I posted got any up- nor downvotes. But now I've gotten two comments, so I know that the site is functional. One comment was "your're not funny" and the other was "attentionwhore" 
So, I dunno. I like your comic btw.
