well i have a few different types of sites.
a couple of them are 'informational' - with articles/content written by me, not MFA srapper stuff - i've always linked out to good resources on these sites, it is one of the things that makes those sites good, i link out on the actual article pages, they seem to rank fine, of course people solicit me for links or exchanges all the time and almost without exception i never give these people a link, not because i don't like link requests but because i don't like their sites. i usually find decent sites by researching my niche and when i do i give them a link.
now i'm not saying i do this on retail/ecommerce sites, i think it entirely depends on the objective of the site.
