Any other independent grassroots journalism websites out there gotten into Google News?
I don't have the link handy, but last I looked they were accepting applications. It's a good way to get your website seen by people who use Google News to scan a whole pile of newspapers (er, websites) at a time.
Maybe a how-to on the submission process is in order? If there's interest, I could write something up.

If you're not using tags or taxonomy on your content, I urge you to start. Not only does it make it easier for people users to find things on your site (see the MFP 'Index'), it allows Google's robots to classify information from your site. I find a get a decent amount of traffic from 'long tail' searches.
Every so often, I study the terms people are using to find the site, and incorporate them into tags on the stories.
