Hi Earl, I say go for it! And I'd suggest starting with WordPress right away, either on your local system, or with WordPress.com, or sign up with one of the many hosting providers, then use a one-click installer to setup your self-hosted site. I say this because it'll save you the hassle of porting your content over at a later stage.
If you'd like to develop your content before you make it public, that's possible too: just save your posts as "Drafts" or set them to "Private" until you're ready for prime time.
I run several WordPress sites myself, and I find it an ideal way to organise my brain (too many interests you know...). Take a look if you like:
- JAY VERSLUIS - it's about 3D and 2D software, anything to do with DAZ Studio, Blender, Carrara, Photoshop and the likes
- iOS Dev Diary - it's about iOS Development
- The WP Guru - it's about WordPress, web hosting, Linux, PHP and related stuff
I write these as if they were entries in a notebook, and I do this because I don't want to forget things when I find a new tip or trick about this and that. If you have any questions about any aspect of the whole thing, creative to technical, let me know.
And good luck with your project!
