Flickr is about the best thing ever, and I'm glad to see all of my coworkers discovering how wonderful it is and having fun with it. I have a pro account, and it's the only online service I actually pay money for. I've always loved to take pictures and share them with friends, but it wasn't always so easy getting someone to sit down and look through a photo album with you. Now my friends can enjoy my pictures at their leisure! Also, it's really exciting when someone you don't know finds a picture you took and either comments on it, marks it as a favorite, or uses it on their website or blog. This blog used my photo, and so did this article. Very cool!
So that's Thing #5, and now I'm moving on to Thing #6 - playing with Flickr mashups!
