I think the caveat (in regards to geocities anyway) is that a lot of sites on there were made years ago, and likely not maintained, which in-turn may be the case of the people that linked to the sites.

yes, that does seem to be a problem. Quite a few sites that were last updated 8 to 10 years ago. Is there a way to do a google query that will find sites that have been updated since, say, 2009?

As for other domains, any that contain a year < 2011 might be a good shout. There are plenty domains with savvy setups that get a lot of the decent domains mind you.

Can you elaborate on that? I am not sure I understand you.
