(Bonus) Who Is Chris Messina?

As I said on Friday's show, I figured that since Chris Messina has been co-hosting with me for about a year, maybe it's time to republish the Internet History Podcast episode I did with him. After all, many of you might know him as the inventor of the hashtag, but did you know about all of the early Web 2.0 stuff he did? It might help you better understand the perspective Chris brings to our interview episodes.
