Speaking of tipsters, an email response to my post about CircumNav pointed me to Inrix, another startup taking on traffic. Inrix is also incredibly cool, and very different. So look for a Release 1.0 Rafe's Radar column on CircumNav and Inrix shortly.
To be honest, when I first started posting blog entries on topics I was writing full columns on, I was a bit afraid that the blog would steal my column's mojo. But I'm finding the reality is just the reverse -- I'm getting great feedback on projects I'm working on before they are due to my editors, leading to better columns (I think). It totally rocks. Dan Gillmor, you were right!
