Oh wow, I actually made it. I gather that More 23 Things took about a month longer to complete than the original set. In my case, anyway, I see that the original 23 Things took place over the summer, while More 23 Things was running during winter and spring. It was easier for me to work on these sorts of things during the summer; earlier, I was in class and had less time and energy.
Overall, I enjoyed the program. I think each Thing needs to be fairly simple and straightforward though. Twitter felt like it had gotten out of hand. I enjoyed Books 2.0 and Bloggers' Toolkit, but it took way too much of that precious time and energy stuff to look at a good sample of the possibilities for either Thing. By comparison, Screencasting and Online TV & Video felt so much more manageable. It might've worked better if each Thing only mentioned a few activities or sites with the rest in a sort of "appendix" to each Thing.
As with the original 23 Things, I don't see our library getting much use out of most of these Things, although we've started Twittering and I suspect we'll find a use for screencasting. Personally, though, I'll be listening to Internent radio, watching online TV, discussing my travels online, and so on. It was a great introduction to Library 2.0 and Web 2.0; thank you.
