...although there was a more in depth discussion that I cannot find anymore.
It appears that some believe (not necessarily my opinion though) that G might be analyzing a percentage of 2 way links and demoting a site for this. In other words, requiring a recprocal link to get in your directory would increase the percentage of 2 way links. 100% reciprocal may be bad. 50% (where 50% of the links are 2 way and the other 50% are just incoming) may be better. Could even be a sliding type of penaltly or downgrade.
I have 2 sites with directories, one requires a recip back the other does not. The one that is required took a hit from #1 to #8 for a competative search. The other that does not require a recip back (it's about 50% 2 way) didn't budge in the SERPs. Could be many factors that aren't even related for this. But who knows?
