Social networking and photo sharing–it’s complicated, at best. I’m using the free WordPress for my blog, in case I run my own WP server again. Facebook definitely has a learning curve to it. I’ll have to get back to LinkedIn one day. I have not yet found a use for Twitter.
For my photos there is Flickr (links to WordPress), Picasa (works on our TV), Gallery 2 (I would have to set up my own server again), Nikon, Shaw (our ISP), and more.
