One of the cool things you can do with Flickr is to browse by the tags you and other users apply to each of your photos. This allows very cool things like this:
collection of photos marked RNC (ie: from the demonstrations in NYC).
Another cool thing it does is the random photoroll that I now have on the right side of the screen here. I held out for a while, but I have really been going in for the bloggy whistles and bells lately. what’s come over me?
