Last summer, Pennsylvania's Tourism Department got a great idea: hire regular folks to take trips in the state, and to blog those trips. I talked to someone in the communications department a few months ago, and apparently the "mainstream media" attention for the project was huge. Which leads me to another reason to start blogging and podcasting now. Blogs and podcasts are hot. They'll garner you attention, just by the sheer weight of the words "blog" and "podcast." If you keep piddling around and waiting to figure it out, you'll miss out on that opportunity.
And you know what? You'll end up blogging and podcasting anyway, because it's the right thing to do. So do it now and get it over with. And if you really aren't sure how to do it, and that's holding you back, just email me and I'll make some time to explain it to you.
