Do you Flickr?

Here's one of my friend Gregory's first Flickr pics, posted (and showing up in an rss feed no-less) within 5 minutes of my inviting him to see my picture stream.

If I loved Flickr any more I'd have to marry it. They've really thought clearly about the ways people might want to get photos in and out of their sites, and they even make blogging images easy. I'm impressed too by the lack-of-friction in signing up friends to the site.
