If you just looked at today's cool link, discussing why editors at Old Media don't seem to get the value of links (but their salespeople litter online magazines with paid ones) I give you this great example:

Esquire magazine interviews our own Andrea Kuszewski and it appears online (in one of those horrid slideshows that annoys everyone yet has survived for 15 years) but they don't put a link.

We still link to them.  Because we are awesome like that.
