Well, when creating a SQL Server Alert, the options currently include email, pager, SMS message, and Net Send. Tweets are typically for public broadcast. SMS messages are equivalent in functionality, but I think more appropriate for sending messages to a DBA, because they can more easily be received on a cell phone. Would anyone find value in adding Tweet as an option for alerts? Perhaps in a senario where you want to send Tweets to a group of users?
