If you’re like me and are immersed in social networking and Web 2.0, then you should know what Twitter is. For those of you who don’t, I’ll try to explain it in as simple terms as possible.

Twitter allows you to “micro-blog.” That is, to create a profile on Twitter.com and the constantly feed it with your current thoughts in 140 characters or less. There are no photos, no video–it’s simply just a running text feed of your current status. Sort of like your Facebook feed, but you can port your Twitter status updates into Facebook and other social networks, while you can’t yet do the reverse with your MySpace or Facebook status updates.

With Twitter, you can follow people’s feeds and they can follow yours. I’m following a few hundred digerati, DJs and music industry professionals and have reached over 1,000 posts. Twitter has become such a phenomenon, that the site has had difficulty as of late staying online. The criticism is that they built the site using Ruby On Rails server technology, which is said to not scale as efficiently as other technologies available. Nevertheless, Twitter just raised a $15 Million round of funding and that should quiet the critics and hopefully smooth out their operations.

What’s great about Twitter is that people from all over the world are already jumping on the bandwagon, typing in the minutiae of their lives. My girlfriend, Missy, thinks Twitter is useless. That is, until a blogger in Egypt twittered that he’d been unfairly arrested. The “twitterspehere” the blogger operates in quickly came to his rescue. That changed Missy’s mind (for now). That is, until she sees me post something about her…lol.

Anyway, the point of the story. Yes…I’m getting to the point here, is that the user @aztrovoi contacted me through Twitter–all the way from Mexico. Who knew I had fans in Mexico!

Why the “@” symbol? Twitter uses the “@” symbol to allow sending direct messages to folks. So, if you want to post and address your post to me so that I see it in my “Replies” box, just put the “@” symbol in front of my user name: djtonyz. The message will go to both community and me.

The power of Web 2.0 is amazing. So many of my friends and colleagues are now following my updates through Twitter, Facebook, MySpace, LinkedIn and many other networks I’m part of. This gives me the ability to communicate what’s happening in my world everyday, and helps all my contacts stay up on my status.

Sure, it’s a lot of work constantly managing your online life. But, the means justifies the end! As I begin to build my off line DJ career again, all these tools have become necessary to promote and market oneself. You have to take advantage of them, because that’s where the people are.
