As many of you know, Twitter has revolutionized the way information is disseminated. It's ability to deliver relevant, valued content direct to desktop or mobile in real-time is unprecedented and changing the way consumers absorb information. No longer is the end user required to seek information by going to a particular source. To maintain being relevant that source needs to come to the end user and today, that is done via Twitter.
Personally, I used to have the time to go through my Google Reader/Blog Roll everyday but those days are long gone. From a time management standpoint I find the blogs I still read are the ones I am aware of that have posted something new. How do I become aware something new has been posted? You guessed it, my Twitter time line, which I check numerous times per day. The more pertinent question is as a blogger, why wouldn't you? You increase your audience, reach and site statistics. You can engage and aggregate an audience you might not have reached other wise and most importantly, you stay relevant.
I honestly don't mean this to be a slap in the face or condescending to any of my fellow bloggers not utilizing this but instead to implore and encourage you to do so. It's extremely easy. I use Twitterfeed it takes literally seconds to set up, is totally turnkey and you never bother with it again.
As a blogger, what you have to say matters. It matters to me and it matters to your other readers. You've chosen to use your voice for a reason. Why institute a self-imposed gag order on yourself by not broadcasting your message in real time, to a wider audience?
