How not to do it: Joe Biden's blog is press release land. It's all about the nitty gritty mechanics that get people inside D.C. excited but nobody in the real world.
How to do it: Barack Obama's blog recently added Nation writer Sam Graham-Felsen and it's the first blog of the '08 season that reads like what we loved so much about the Dean blog. Real stories from real people and an actual back-and-forth exchange of content.
Strangely none of the "top tier" Republican candidates have blogs.
FOR WHAT IT'S WORTH Biden is putting Youtube to good use.
