For those of you who are trusting souls, like me, here is a word of caution: keep a very close eye on the reciprocal links that you are supposed to have posted on others' sites. Check them frequently. It seems there are a significant number of webmasters who are removing their link partners'links on the sly. This gives them a non-reciprocal back link, which might benefit their page rank, but certainly not yours. It would be wise to make sure your links haven't "conveniently disappeared" from your link partners' websites.
