Jumping Around

I have found myself jumping around in the "23 Things." But, no matter which I go to there are already several people ahead of me. I have enjoyed figuring out how to use everything. I am creating accounts in every tool suggested. Even though I already use an equivalent website. For example, I already use Google Reader. I am curious to see if I will like Bloglines better. I have found that I do not care for PBWiki. Everytime I explore and try something it tells me that I need to upgrade.
