He's had several really good ones, most recently showing off a really cute Google Maps hack. Well more than cute: impressive and very instructive.
Anyway, I'm trying my hand at this in practice, both to learn about the new medium and to illustrate some BlogBridge features.
After a bunch of false starts, playing with tools and utilities and microphones that aren't on here's my first quasi-successful attempt. I don't think it's quite practical yet. For one, at 6Meg it's way too big.
But it is an interesting start. I will continue to look at it and report as I go.
