Hmmm, they're sort of cute, but also sort of creepy. Not sure I'd 100% trust those guys. Especially if there were 7 or 8 of them working together.
DTube doesn't work well for me, never has. Most people find that. It's barely adequate. Somebody really needs to come along and do it better, and DTube will crumple and disappear. Until then, we re-upload, we try again, we manually add a thumbnail, and so on. :)
