Well, I think I've covered all 23 Things and I know I learned a lot. I'm just not sure how useful most of it will be to me but it's nice to be aware of all the possibilities out there. If I spent more time in front of the computer, I might explore a few of these items, but most of the things were odd and not of interest to me. It would be more inviting if you didn't have to keep creating new logins and passwords for each new thing you want to try.
