Further automation suggestion:
1) tie the blog database in with a list of each blog's keywords.
2) From the above, auto generate (number of) articles for every blog and email them out at intervals of (x) hours (with a bit of a random factor).
3) Pre-sending approval queue, so you can cast an eye over the articles before sending them out, and respin them if necessary.
...yes, I am that lazy.

I'm up for a beta-test too.
