I think that Reddit tends to have a bit higher level of users than the typical site. The mods of each group spend a lot of time curating the content - unpaid. Most users and Reddit itself know that pissing off the majority of this group that actually produces their product for free could have negative consequences, and they'd end up like Digg without much warning. It seems that Reddit's way forward is not with ads or affiliate links, but paid content in the form of up voted articles and comments. It's becoming quite noticeable.
