Inlinks.com finally came out of it's beta version, showing the world how to buy and sell links in an editorial controlled environment.
Here's how it works:
Online marketers, webmasters and SEO's can now buy relevant links within context. Bloggers can approve or disapprove these links (and finally make some money out of their content).
For the users this means relevant links within relevant content, but without any popups or layers.
Long story short: Inlinks seems to be a great way to drive traffic without upsetting the users. It also helps with ranking in the search engines.
Even if Google is not the best friend of paid links, out of a user perspective I don't see what's wrong with links in relevant, editorial approved content.
