Twitterish 

An adjective used to describe someone (very) active on Twitter.

For the average internet-goer, being Twitterish only lasts for a short period of time after a Twitter account is acquired.

Becoming Twitterish may occur after someone realizes that have a large sum of followers (more than one), and feel that they would be let down if that someone doesn't tweet.
