I would double check most of these suggestions for "mentions" across the forums...

Sammy,

From my experience, OpenPress.com & PRBot.com appear to be the same owners/company. I found their site quite busy and confusing.

Your third mention (24-7pressrelease.com) should have been your first one! We tried their $25 contribution as a sample and we found some great exposure. They also have a great easy to use layout!

Just from my own experience, we have used a new program (we were a little skeptical at first, with the cost), that a site http://www.24-7pressrelease.com has called their Mass Media Distribution program. I think they may be affiliated some how with PR Newswire. Anyway, the point being, I performed a search on our headlines and found our news release really did hit alot of places. Some of them with page rank, some without. They also sent us an email shortly after the release went out to links to about 10 major sites including CBS Marketwatch, Yahoo and others.

I don't know how long the links hang around afterwards, but we appeared to get some decent interest and traffic and in fact had an interview from a small paper in Nevada!

I guess it really depends who your release goes through, but my own personal experience is it worked well and I would do it again.

Or maybe it worked just because I am a girl. :-)
