Confession of a Twitter junkie...
I love Twitter & have met some really interesting people through there. One author I'd been following his career for years, touched base with me through Twitter. And of course, now I'm planning the Int'l Food Blogger Conference...a number of our sponsors have come via Twitter. It's very interesting.
I also use Twitter as a vehicle for all the interesting stuff that comes my way. I write about things I'm doing that never end up in a blog post (artisan butcher field trip, for example), etc.
If you hop on Twitter, I'm SeattleTallPopp. Heather in SF is on there too... as HeatherHAL.
