Some very interesting comments and thanks for sharing.
Those of you with no time, I completely understand and definitely enjoy the rest of your life first. Writing about SQL, especially when you have a job in IT, is a lot to do.
Those that don't feel confident, I'll share something I've seen in my 10 years of writing. If there's a problem that I solved, no matter hot insignificant, chances are that there are 100 or 1000 people with less experience that have or are struggling with it. Something as simple as moving tempdb to a new drive. It's a simple KB article from MS, but not everyone would find it. Or understand it. I wrote an article on it and people might have seen it here, thought it was easier (or harder) to understand than MS' version, and maybe if stuck in their head.
The Internet can definitely make everyone a publisher. And that's very powerful. It can allow you your own voice.
I'd definitely suggest everyone get a technical blog and put down short entries about things you've solved. It's a great way to add to your resume and show that you are knowledgeable. Or show that you're learning. Keep it to technical posts, no posts about your dog, cat, or anything non-technical. We're redoing blogs here and we'd host it or grab a few blogger account if you want. Be sure you set at least a reminder every couple weeks to put something down.
If you find you have time, and you want to take a chance, send me something. You can email or go into the "My Account" in the upper left and submit something. I'll edit it, give you feedback, and help you get an article published and your name on the front page. I still get a kick out of it and I'm sure you will as well.
