feel about links from indirectly related sites
If the link would reach users who are well-targeted for what you're offering, then consider it a good link.
If the link would make good sense to human users, eventually it will make sense to the search engines too, even if the relevance is indirect.
The first time someone with a page about "venison recipes" linked to a site about "hunting gear" or vice versa, the search engines likely didn't know what to make of it. But the targeting is logical enough that sooner or later a pattern would emerge which the algos could identify.
