I actually re-evaluated my links page the other day, and found that in many cases I was giving away a lot more than I was getting back. Some of these were set up when my site was very new and I was gaining at that time, but as it has progressed and these other sites haven't, the situation is different now. So I deleted all those that I didn't want any more, and have just 55 left. I think I can see a situation in the not too distant future when most of the rest will go as well.
