Here are some other things we hope you have learned:
It really doesn’t take that much time.

Ha. Ha. Ha. No, that is not something I learned.

What I learned was that 23 Things does take a lot of time, even to give the Things a cursory look, and that Thing 20 in particular takes a lot of time even when you don’t explore one site from each category.

I’ve learned about a few useful sites and quite a few more I’m not in a hurry to visit again.

I have no intention of continuing this blog. In my first post I said I’d had something like ten already; on counting them, I find that the number is actually (with this one) 14. I start projects, I lose interest in them, I abandon them. I lost interest in this one around Thing 6, as the actual time to do the Things turned out to be so much more than claimed, and the usefulness of them a bit less than I’d hoped.

Things, in order of usefulness to me (roughly)

Useful:
Thing 5: Flickr (esp. with searches on CC-licensed photos)
Thing 9: Sharing – slides, photos, databases (but Lazybase never works; Blist at least does work, though it only does matches on terms and apparently doesn’t do even inner joins).

Somewhat useful:
Thing 4: RSS and newsreaders
Thing 8: Communication – Web 2.0 Style
Thing 16: Youtube (fun to view videos, painful to read comments)
Thing 17: Podcasts
Thing 18: Facebook and MySpace (MySpace especially, since we don’t get enough spam at work)

May eventually be useful for library work:
Thing 6: Flickr mashups
Thing 7: Online Image Generators
Thing 20: Books 2.0 (most of the sites here don’t do anything particularly interesting, though Reading Trails has potential. And, again, this Thing is entirely too long.
Thing 21: Student 2.0 Tools

I doubt I will ever use these for work at the library:
Thing 3: Blog Search Tools
Thing 13: LibraryThing (nearly any of the sites in Thing 20 do book recommendation much better, as does amazon.com)
Thing 14: Online Productivity Tools (online backup maybe, the rest a solid NO)
Thing 15: Rollyo (doesn’t work)
Thing 19: Other Social Networks (I like BakeSpace, but cooking is not part of my job)

Maybe this all shows nothing more than a failure of imagination on my part–certainly other people can find use in Things that I don’t.
