I read through the comments in that other thread. Seems to be a mixed opinion, but still a lot of weight given to PR when linking. That's too bad.
The theme I do see is that webmasters that are looking to EXCHANGE links are interested in the green. That makes sense because they're trying to increase PR and are less worried about visitor experience.
I don't respond to link EXCHANGE requests, but will gladly link to a site (regardless of PR green) that provides my visitors with a better experience.
I realize a lot of experts here think I'm a complete fool for taking this approach, but it works pretty well over the long haul. (I also don't ever have to worry about a SE penalty for link exchanges.) This approach is based on a mistake I made about seven years ago - never to be repeated again.
