Step 1: Pick a domain and check if it’s free. Try to make it something easy to remember, that you don’t have to spell out to people.
Step 2: Buy a hosting package. I use 1&1 to host, and so far, they’ve been swell. All you’ll probably need is the beginners Linux hosting package, it comes with a domain, 10 MySQL databases, and 10 gigs of space. It’s $3.99 a month (but there’s always specials to be had). You can host elsewhere, just so long as you have a MySQL database and FTP access.
Step 3: Profit! Just kidding. Download the latest from WordPress.org. There’s a bunch of steps here, but rather than just plagiarize, I’m just going to point you in this direction for the general directions, and to here for directions using 1&1 hosting.
Step 4: Time to customize! You can find easy to install themes to make your blog look more “you”. I believe in crossposting, because not everyone is going to put your blog in their RSS Reader, or even use one. Here’s a handy MySpace Crossposter and a Live Journal Cross Poster. I also import my blog’s feed into my Facebook. You probably want to use something like Disqus or IntenseDebate to turn your comments into conversations (I use IntenseDebate and love it). If you make pages such as the ever popular “resume” or “about me” pages, you may want to checkout this post on removing the comments section from the bottom of a post. If you see any customization on my blog that you’re curious how I’ve done, let me know.
I’ll try to expand on this as I learn more myself, but for now this should definaely get you on the right track. Happy blogging!
