There are alot of good ideas in this forum, both negative and positive.
But let me tell you from experience that three way linking is the silver bullet of the SEO industry. The real successful people do not reciprocal, but perform one way and three-way-link exchanges which are golden.
If you get quality, themed three way links, you are going to rise to the top pretty quickly.
Anyways, you know the website: www.three-way-links.com
... decide for yourselves. If you don't want to trade that's just fine.. but if you do, come on in and lets setup some intelligent partnerships.
