Flickr

The more I look at Flickr, the more it reminds me of Google Images - lots of stuff, but no context. So if you want a generic picture of a cat, you can get one. If you want a picture of something older, or specific, it gets harder - it all depends on the metadata (tags).
I admit with a background as a photo archivist, I'm pickier than most. And as a new grad/teacher, I'm even pickier. But I did run across Slideshare, which I like much more! You can share PPt presentations there , so there's content and context. Here's one on library 2.0

TechThots - at the moment my mind is filled with Archivist's Toolkit, which is an open source program. It's not immensely more sophisticated than relational Access, but it is pre-configured, and it does have a good fast-data-entry interface. What I really like is - it's OS. What I really don't like is - there's no Idiots Guide.
I'm also running around with my new digital camera - ooohh, 19.95 is an upgrade for me, notice I'm an archivist, not a photographer. Look for a slide show to come :)
