How about food blogs?
Unlike an earlier wave of food blogs focused on home cooking, recipes and basic restaurant recommendations, the new breed is gossipy and competitive; it trafficks in pointed restaurant criticism and tidbits of news - Craftsteak has installed a new stove! Emmerite beans have been added to the menu at Tasting Room! - and is unsettling the ground of the restaurant industry.
Speaking of which, do you think there are too many Thai restaurants or what? Ha. :)
