I'd say that we not read "too much" into this. Google is targeting specific groups of webmasters/websites. Reciprocal link exchange will continue as it has been. Those that have crossed the threshold are the ones that need be concerned. Now, determining that threshold is the key. But, why even bother finding out what that threshold is? Just link naturally and all "should" be fine. Sounds easy, huh?
