Are any of you still using SB with AA blogs?

Obviously not on your money site, but I'm wondering if they're still useful for anything: like getting your lower tiered links indexed?

I've heard that those types of links have no value at all, and that they instead harm sites, and also that they only have value when linking to an authority / established site (like wordpress, etc.) - Just wondering what all of your thoughts are on this?

Specifically, I'm thinking of using them to get my tier 2 links (social bookmarks) indexed, do you think it's a good idea?

Thanks, BHW!
