FoodFeed is a micro service for Twitter.com users. It allows you to record meals and track what others eat. As the developers themselves say: "There is no benefit, but it's fun." Anything you need:
add a having in friends
create your own page on the service website by going to: http://username.foodfeed.us/ , where, as you understand, username is your Twitter.com nickname;
each time you want to share your gastronomic preferences, write to the user having (you can do it in the usual way: " @having ", or you can directly: " d having ");
track your food trends on the above page: http://username.foodfeed.us/ .
The disadvantages include the inability to write in Cyrillic, and the advantages of being able to import an emerging tape anywhere (via RSS).
