too many follow links, indeed, not good. I would do the same what [matt cuts][1] said about rel=nofollow. **As long as it has no relevant content**, I would let it with follow link. For me, the content is everything (and learn always how to write effectively and useful for others) and from the best content, we have high possibility to earn backlink like others do.

As you know that with no relevant niche, the links have small effect in PR.
