Re: where to start learning
I second the WP Blog if you are a do-it-yourselfer, it's got a lot of community support, and you can do a lot with it.
Eventually (Hopefully) you will become so busy (The rewards of your effort) that you are not able to maintain what you have started, and that is where a professional firm takes over and you will likely switch away from WP or turn that WP into just your on site blog, but as a starting platform, you can't really go wrong.
Starting LEC 7 soon but it won't be called LEC 7 - LEC 2012 coming soon!
