Visit ProBlogger then search for their series "31 Days to Building a Better Blog". They link to several other blogs and have ALOT of comments from readers about what to do and not do and how to do it, etc., etc., ad nauseum. Exactly what I was looking for.
And after reading several things, I come to the conclusion. I have NO REASON to write this. I'm not an expert at anything except how to be broke (well, that's probably not true but that's how it's felt lately). I like computers and gadgets but I don't even own a cellphone and I'm not a massive technophile. I don't run a business. I haven't a degree in anything at all. I read alot (a book a day for 20 years enough for you?). I haven't a great sense of humor or very strong political views.
So what do I have to offer anyone besides myself?
This blog is about someone depressing normal. I've been a housewife forever (mostly through an inability to keep a job) who plays computer games, enjoys the communities she finds on the internet and has learned to live ok on less than most people spend on a car in a year.
But I have to do SOMETHING. Life has finally reached the point where I'm sick of being broke constantly and my circumstances mean trying to get one more job is unlikely although I am trying (How do you look for work without a car anyhow?).
Hence, this attempt to become something larger than myself. What will this be about? Me, my family, the things I find online that make a frugal life easier, my trials with the Social Security Department as I apply for SSI, attempts here and there to make cash online somehow someway at all. (I'm open to ideas if you have any.) Me. It's about me. Something I know everything about 
Update two days later: There is something I know about, have had years of practice at, how to live for less. My family has never made more than fourteen thousand a year or had less than three people in it. That's less than five thousand a year per person. Saving money has become something of a necessity and I certainly know how to do it.
