Where to start?
I think with the work and effort you are putting in getting a domain and using wordpress maybe your best options in terms of scalability and workability.
You need to get facts straight so makes sense using wiki etc and that is fine as long as you write it in your own words.
Would you consider moving to wordpress on your own domain? If not I can give you some tips but blogger is so limiting and you never own your content b/c at anytime it *could* be gone.
Moving from Blogger to Wordpress - made it !
I'd read that post and ask any questions you may have in the Blogging Basics forum. Zhuli or anyone else who has made the move could help you. There are guides out there as well I believe.
