SE hits to my freesites just keep on growing. Over the past year and a half I've submitted to some 150 LLs (currently down to about 24). Right now Google is my #5 referrer and Yahoo is #10, both ahead of some pretty big LLs that I submit to (and get accepted at) regularly.
Once a freesite has been out there for a month or two it usually picks up some PR and I have plenty of freesites with PR3.
The only SEO I do is put up some relevant text, make sure all the metas are matching and use <alt> and <title> tags and such. I don't know what else I can do, but the SEs seem to notice.
