Content recommendation: I do talk about Amazon having a book recommendation service. What I was talking about was an enhanced version that recommends not only books that you can buy but other related sources. Sort of like a content search engine. If such a feature is available on Kindle, I have failed to see it.

As far as the notes are concerned, I was talking about virtual stickies. I believe I pointed to that as well. If there is such a feature available on Kindle, I stand corrected here

You can already take notes for any book and the Kindle keeps track of them (and you can copy to your desktop, if needed there).

And it has had book recommendations in the Kindle store since I’ve owned mine (and probably since day one, as helping you make purchase decisions is the #1 job at Amazon).

For social media, it would be nice if you could push your library out to librarything or shelfari (to merge with non-kindle and non-amazon content), but otherwise you really need to get something with a fast refresh (and color) … in other words, a PC that isn’t as good at being a reading device. As for twitter, no thanks. Who wants constant interruptions of “I’m feeding my cat” or “should I eat this or that” while trying to read? You attention span is probably already shot from the constant IM/text/twitter traffic you have now, why ruin the one experience you may have that shuts it all out? Besides, once twitter is overrun with spam (like the email and IM it replaces), it’ll be a dead/less useful technology as well.
