I'd like to start a blog, but I've no idea how. Brian Moran
There are plenty of "how to start a blog" guides on the web. Three good examples are:
How To Blog: A Beginner's Blog Publishing Guide
How to Start a Blog (WikiHow)
How to Start a Blog (Working Smart, Michael Hyatt)
However, I'd suggest running a disposable test blog for a week or two to get the idea before you tackle something serious. Blogger (http://www.blogger.com/) is still one of the simplest places to start, and it's free. You can sign in with a Google account.
