Love it when my worlds collide like this. Loic Lemeur (Mr. Seesmic.com) posted a seesmic video wherein he's showing Michael Tchao (of Nikeplus) how seesmic works and talks about the number of runners on Seesmic.
I'm a HUGE fan of Nikeplus and have found it invaluable in my own training. If it's not too late tonight, I'll have to post a response to Loic's video to say hi and share my own Nikeplus story. (I run on Asics, btw).
