Regarding Flickr - I realize that everything is owned by someone, and usually one of the big kids, but come on, how many email and user accounts do I have to subscribe to before I am a social, savvy being?
Flickr is an interesting medium for sharing. Like many other sites and activities it is easy to get sucked into --I just spent 10 minutes watching stpiduko's "People I Asked" http://www.flickr.com/photos/eamon/sets/72157594526998899/ it's an amazing collection of photographs of people far and wide, strange and not so strange. But really, was it worth 20 minutes (yeah, I got sucked in again) of my life? Sure --this woman's tattoo is amazing! I'm really more voyeur than social networker - I have no desire to tell stpiduko how fabulous he is (surely he's heard that by now) so I'm not really being social am I? To loosely refer to John Bender - where do the lines fall between demented, sad and social?
P.S. My attempts to post Flickr images with the URL option were wholly unsuccessful... so much for technically savvy.
