I love my Twitter friends.  I had a clue what twitter hashtags were based on context, but I wasn’t sure how formalized it is.  Well, I just asked my followers on Twitter and I got replies almost immediately from @afhill, @troyturner, @AnnOhio (Ann hates them). Actually, in addition to the useful content over at Hashtags.org and the Twitter Wiki, my new best friend Andrea Hill actually hooked me up with her blog post about Hash Tags: what’s the deal with… #hashtags on twitter?:

In an effort to make the service more powerful, some conventions are being established. Most people recognize “@username” to be a reference to a specific user on twitter (and their name will be linked to their account). Something else users may see are hashes (#) before words. My first exposure to this lead me to hashtags.org (another similar service is twemes). Hashtags.org is an opt-in service. A twitterer can follow @hashtags, and then may use hashtags.org to track realtime tweets that reference that specific hashtags. I’ve seen people throw hashes in front of half of the words in their tweets, to try to leverage this tracking.

I am still on the fence.  Here’s some advice: if you know that your event or group already has a Twitter account, then use the @ sign, @podcampohio, for example. However, if you’re doing your self-organization spontaneously and via Twitter only — let’s say I decided to append all of my Tweets with #amtrak while I am on the train to NY this morning, for example — then you should probably use a Hashtag.

Finally, if you want your Hashtags to be tracked real-time by the gang at Hashtags.org, you must follow @hashtags for the service to index your tweets. An, if you don’t know what Twitter is, you need to read this Twitter Primer. Oh, and if you should decide to become a Twitterati, then please follow me at @chrisabraham!
