Yes ask me! If you have a paid lj account then you can create lj rss 'journals' that you can add to your friendslist. (It's just a case of finding the rss link on whatever blog it is, usually the orange square with white bits on it, then pasting this into the appropriate box in lj)

I prefer getting comments on my tumblr, just for the fact that I automatically get email notifications there and don't on the lj feed. But what's even better than comments is seeing other people propagate the video saying 'hey everyone this is ZAWESOMEZ all must see it'. Alas this sort of video doesn't come along that often and I have to make do with mocking rubbish ones.
