I’m sure you’ve heard about twitter but you may not know how it works. Basically, it’s a social networking service and when you choose to be a follower of Green Street you will receive occasional tweets. A tweet is a short (140 character maximum) message that I will send out. Note I said occasional. I will not bother you with mundane messages (such as….”just sold another Dianne Salad”) but I will “tweet’ about the things I think you will want to know and offer followers some special invites and deals.
