A twitter user who uses the hashtag for any purpose, but typically to develop a topic of their own making into a meme or to self-promote.
The hashers were out in force when moonfruit was offering a free laptop to people who included the tag "#moonfruit" in their tweet, resulting in a lot of positive PR for them.
