The blog is quiet for a number of reasons, including
* I have moved to using Twitter (@scilib) and FriendFeed a lot more for sharing information
* I have a new iPhone and as I discussed in my Twitter modes posting, short-posting services like Twitter are a more natural match for using on mobile devices. You can blog from an iPhone, but it would take a lot of patience to tap a long posting out on the virtual on-screen keyboard.
* Reason I can't tell you which will be announced soon
This does point out one really unfortunate thing about Twitter search - it's not like Google, it doesn't go forever back in time. It is intentionally limited to recent tweets. So it looks like there was only one #icsti2009 tweet, when there were actually dozens, as you can see in the archive on FriendFeed. (In fact making a FriendFeed room is one way to get some preservation of your tweets, although I believe FF search also doesn't cover all the way back in time either.)
And I recognize that Twitter is a much noiser information channel, full of half-formed thoughts, asides and insider person-to-person conversations. The blog is still the best platform for long-form thoughts.
