What is the # on twitter for?

[arshak anjum]

A hash tag is simply a way for people to search for tweets that have a common topic. For example, if you search on #LOST (or #Lost or #lost, because it's not case-sensitive), you'll get a list of tweets related to the TV show. What you won't get are tweets that say "I lost my wallet yesterday" because "lost" isn't preceded by the hash tag.

It makes a link out of the word and it helps people find other tweets about the topic. I like to run, and whenever my tweet has the hash tag i get follow requests and tweets from other runners on twitter. Kind of an attention getter
