Not really. Well, I think they use Tumblr rather that those other platforms because it's very, very easy to post different kinds of media, and because it's more social than the other two (in the sense of being able to subscribe to people's Tumblrs easily -- all blogs have RSS, but Tumblr packages all your subscribed tumblrs right there on your Dashboard). As for the comments, I'm not sure but I don't think they were available at first. Now they're available but apparently not on by default, and I suspect people are used to using Tumblr without them so they just don't think to enable them.
ETA: Actually, you have to kind of hack comments in by adding Disqus, and not all themes support it. So, yeah. Most people aren't going to do that.
Hmm. I'm not sure I'd say that being able to subscribe to a blog more easily makes that blog "more social," expecially given that you can't freaking comment on most of them. But then I am apparently an ornery old cuss who misses the heydey of blogging. ;)
It's more ... I don't know, network-y? I'm not much of a Tumblr user myself, but I use Twitter and it seems like it has some similarities (except that you can *reply* on Twitter). I just don't think Tumblr's meant to be a conversation as much as "a bunch of people sharing cool things they made and/or came across with the world." (And then NOT TALKING ABOUT THEM, which is the part that drives people like you and me nuts.)
Ahhh, that explains a lot, including why I knew I'd seen commenting available on tumblrs before, when it doesn't seem to be possible on most of the ones I'm looking at now. Glad I'm not crazy!
