Yes, my enthusiasm for this whole challenge (Learning 2.0) seems to be growing! Would have to say I really enjoyed both del.icio.us and Library Thing — the latter in particular! I’ve started bookmarking and tagging with deli.icio.us, and put in a few eccentric choices in Library Thing. Looks like you could use up enormous chunks of time hanging out on Library Thing. If you want to see my stuff: http://del.icio.us.nowrnevr and http://www.librarything.com/catalog/nowrnevr. Enjoy!
