Ad system: Entrecard

I'm always looking for cool and interesting methods advertising my blog and whatnot, and I was floating around There's A Blog In My Soup!, and looked at a few of Patrick's adverts, and saw this Entrecard thing, and decided to check it out. It's a pretty interesting method of exchanging "digital business cards", and gaining exposure for your site through showing ads for others through a widget on your site (mine is below the Random Links of Goodness block in the sidebar).

You have full approval of who appears on your widget, and you control that through your Dashboard on the Entrecard website. Gives you stats, you can view the profiles of the advertisers' profiles, etc etc. Pretty interesting stuff.

I'm just starting to investigate the program, and as I develop some better sense of how well it works, I'll post those results.

If anyone else has any cool methods for internet marketing, link exchanging, etc etc, please by all means comment here or email me, and we'll hook it up.
