Why use Twitter hash tags?

9 May 2009

To add a hash tag to your Twitter update you just need to add a hash "#" and then the tag - like if it's a PHP tweet you can write at the end #php

But why use hash tags, they only seem to use up more of my characters and only being limited to 140 characters to start with is hard enough already!

Hash tags are the easiest ways to follow a conversation on Twitter.

Most popular hash tags are now shown down the right hand column on Twitter's home page (when logged in) and these show you the most talked about topics on Twitter.

If you want to join in the conversation you just need to use the same hash tag.

From a hash tag search you can also save a search, which will let you go back to the search quickly to see any progress in the conversations, or at the bottom of the right hand column there's a link saying "RSS feed for this query".

Clicking this link will allow you to subscribe to the RSS feed, and then you can get the updates on your chosen subject direct to you RSS feed reader. Now you can always be up-to-date with your latest interests.
