If reciprocal linking is fine than 3-way linking should be fine, too.
Good Reciprocal Linking:My site sells refrigerators. Another site sells appliance bulbs. We arrange for my site to refer customers to them for bulbs, and they will recommend me for appliances. It's a business arrangement that benefits us both, we each link to the other site. Whether or not the search engines like it, we are sending business to each other. If the link no longer "counts" in the SE's one day, it doesn't really matter.
Crappy Reciprocal LinkingI want links to make the engines think my site is really good. I accept links from anyone and everyone who agrees to link back to me. The search engines devalue reciprocal links and I curse them for taking food off my table and whine to anyone who will listen about how unfair it all is.
Good 3-way Linking:I can't think of a situation in which this will send any more business to my site. If site A and site B are relevant to my customers, why wouldn't I link to both of them and have them link back? If neither are relevant... why would I bother?
Bad 3-way Linking:I try to fool the engines into thinking I don't have reciprocal links so that they are not devauled. However, the engines study linking patterns and communities, and my neat little plan is foiled. I might even lose rankings because the SE's suddenly think my appliance site is about gambling/viagra/hair growth remedies/scrapbooking/travel in Vienna/Rolex watches (because who
I link
to is completely under my control and I think these sites are important enough to link to) and it reduces my standing in the appliance listings. I whine and stomp my feet and try to get a class action suit against the search engines for dropping my rankings.
Anything you do that brings
real business to your site is good, regardless what the search engines do. If they drop links as a metric altogether, my links still drive real traffic and business, instead of being an embarrassment that I try to hide my links page by only linking to it via a sitemap.
