My reasoning is that I just don't need the full power of a total CMS system. All I really require is some blogging software to post progress, with some static pages for things like articles and game pages (possibly with commenting). WordPress will easily allow me to do all that.
Furthermore, there's the whole time issue. If I have to choose between spending my time managing a website, or actually doing something worthy to post about on the website, I'd choose the later. From the looks of the more advanced CMS systems I reckon it would take me weeks to get them properly set up, and that's time I can't really afford right now.
I'll start crafting the new site on the weekend. My current inclination is to make the journal itself the front page (since that's what a regular visitor will be wanting to see), so the location of this journal may change.
