Sorry but, Lilli. YouTube is for 12 year olds, imho. I was at the library the other day and after about 2:45 pm, the inundation began! (School lets out) Out of curiosity, I walked around looking at some of their screens, and almost every one was "tuned into" YouTube or if not that, some inane junior high level cartoon thing. I've read some of the comment threads too, related to HRC or BO or McCain videos -- some are almost embarrassing.
The grown-ups, m'dear, are found at HuffingtonPost, Salon, Democratic Underground or other similar political / cultural sites. Plus, of course, on here, we all 'know' each other. And there is something to be said for a certain comfort level, after all. Even when we are all hurling bricks at each other! hugs back, as ever, "L."
