As confirmed by the Mets and MLB, GM Sandy Alderson has created a Twitter account.  Judging by his first two tweets, this could get interesting.https://twitter.com/#!/MetsGM/status/167706506517680130https://twitter.com/#!/MetsGM/status/167720412438999040Most interpreted his first tweet as a joke about the monetarily-challenged Mets organization.  I interpreted it as a joke about high gas prices.  I could just be naive.Regardless, Alderson hopping on Twitter is a good P.R. move for the team.  One can't be sure how much he'll actually share, but time will tell.Getting unprecedented access to players, coaches, managers, and GMs is one of the greatest benefits of Twitter.  R.A. Dickey and Justin Turner, for instance, have been very interactive with Mets fans.
