Wow is this a lot to cover! Why does it have to be paper books vs e books? I think the future holds both and that what is important is that reading, culture, literature, etc continue. The format is not so important: a love of learning, of reading, and of life long learning is what is important (no matter what format we do it in).
I enjoyed my quick tour of many of these book 2.0 ways for sharing the love of books and reading. Books on my phone is a category that I will not be using personally, but will continue to be aware of in order to serve those for whom this is style of connectivity is important. (If we all have different learning styles, I suppose that we all have different communicating styles too: so it is important to be familiar with this technology.) I looked at DailyLit and at Twitterlit. I'm still not a Twitterer, but this Book 2.0 phone game is fun! It reminds me of the podcast "Who Said Literature Game" that I loved so much in the podcasting thing. Getting daily literature sent directly to an individual's phone can be great for those on the go -- if a book's not handy but your phone is this is a great way to keep reading.....
In the Reader's Advisory section, I already use What Do I Read Next (as well as Novelist). So I looked at Reading Trails. I liked it, but it needs to grow: The idea is cool and if anyone had read anything I read to get me started down trails, I would probably never stop. However, too few people (so far) are participating and they don't the same types of things I read (despite my very eclectic reading tastes). I'll keep checking back, who knows, maybe I'll start my own trail -- I like the idea of being a trail blazer.....
I looked at several of the online book communities and am glad to be aware of them but personally will stick with LibraryThing and Goodreads.com.
Book group resources was a wonderful selection of resources. I glanced at each of them and thought that they were very helpful and informative. My absolute favorite, however, was Open Culture. It includes lists (plural lists) of FREE online courses! Oh I will be using this site the rest of my life........
The Book Reviews selection I was less enthused with. I already use several book review sites that were not included in this list. I like the ones I'm using better. Of course I get to them through my bookmarks on my computer at work and I am currently at home so what are the sites I use? Powell's is the only one I remember. But I also just do a google search with the book title in quotes followed by the word review and often find the odd gem that way.
