When Blogging... Where do you begin?

[Devon Cornwall]

Hey BP,

This is a question for all the newbies like me floating around. How does one go about starting a blog?

How do you choose topics to write about? Do I just start it off and work my way through?

For example, I am currently writing my business plan (it is probably 6 pages long) and I have hit stumbling blocks and really dug into the nuances. Do I simply share my learning of those nuances in one place for the next person to read and follow?

Can anyone help me with referrals of site hosts they use, or even of people they have contacted that do website building at reasonable prices.

Thanks in advance,
