You said you thought the either (a) the site was made as a troll, or (b) you couldn’t think of any other reason to have spent time on it, because (c) the content was something you’d get from your (implicitly technically clueless, rural) aunt. The implication was that whoever made this site was wasting their time and ours.
I don’t have any reason to be “already defensive” (I had never heard of this thing before today and I’m definitely not the target audience), and I agree with you that – given the demographic using the site – most of the content is pretty juvenile and uninteresting. But your criticism is mostly content free, and the tone reads as the sort of speculative petty sarcasm that I’d rather avoid on this site.
Anyway, I haven’t seen this idea before: what other site has a front page filled with tiled user-submitted pictures, which when clicked on open up a comment thread wherein each one can be remixed by other users? There are mediated “funny picture” sites like Can Has Cheezburger, and there are general-purpose discussion fora like 4chan and Reddit that include many “funny” pictures, but nothing especially like this current effort, that I’ve seen.
Funny pictures don’t really appeal to me (for that matter, I think the overwhelming majority of the content at facebook, youtube, twitter, reddit, and similar sites is also garbage), but I it’s always interesting to see what kinds of interfaces new community based sites come up with, what kinds of interactions they afford, and how that shapes users’ actions and contributions. There’s more to discuss here than “meh this sucks, it’s probably just a troll.”
