It's a way of organising 'tweets' (what they call status updates on Twitter).

It's like if you tag a photo with keywords to help organise your photos.

All hashtags get parsed and the most popular hashtags are put onto the trending list on Twitter.

Hi $ound Victim,
A hash tag is feature on Twitter used for categorizing or grouping tweets (Twitter updates). An example of a hash tag is #you. So if you want to be part of those talking about Michael Jackson you'll have to use the hash tag #michaeljackson in your tweet (Twitter update). That's how it works.

Hope this helps .
