Twitter food

Love it or hate it, people are using Twitter.  (Hell, we might be getting a GoodGoings twitter account for meet ups and such…)

The Los Angeles Times travel blog does an article about some NorCal street food vendors using twitter to alert customers of their location (the Kogi Truck of course gets a mention), and Serious Eats has a list of street food vendors who use twitter by region of the country.  EatingLA is also keeping a list of Los Angeles foodie tweeters. Are they missing any?  Are they all over rated?
