I am experimenting with a consolidated icon that includes many social networking sites. Would like to compare notes.

Are you using social bookmarking icons? If so, are you using a consolidated icon or putting up images separately?

I'm using AddThis at the moment.

My site is free and as such I am tight-fisted in the marketing department. I don't think PPC would be cost effective for me, at this juncture.
