I follow quite a few local restaurants and/or their chef/owners on twitter. Recently I noticed that a good number of them have a strikingly high proportion of tweets that are just complaints. No real value to the message, just an outlet for bitching about a cancelled reservation, or poor review.
Personally, it turns me off to the establishment. What about you guys? Are you noticing similar things.
btw, I'm @RodzillaReviews - I mostly follow establishments in the Pittsburgh area.
