Flickr

I love looking at photos, my own and other people's, so what could be better than Flickr? BTW Matt, looks like you had a fabulous Caribbean vacation! I've only uploaded a few of my own photos so far, but intend to put them all up so I have a backup in case my computer crashes.
And yes, gov docs librarians are on flickr too. The group Best.Titles.Ever has some interesting pics
