I’m not sure if this is a huge deal or whether it marks the first time Twitter is calling updates such, but I noticed this morning after about 10 a.m. ET that emails from the company began referring to postings on the service as tweets:
At or Before 10 a.m. ET: Updates
After 10 a.m. ET: Tweets
The only reason I noticed, really, is that I administer at least five Twitter accounts and have Gmail filters set up to route them to their proper folders. The filters were based on the wording “Hi, [username]. [Username] is now following your updates on Twitter.” After the change, my Twitter follow alerts started popping up in my regular inbox. Grrrr.
