This is becoming a repeating theme here on HN and it seems like its another way for the people who aren't doing anything to feel like "entrepreneurs". It also seems like what takes place at a lot of conferences these days and especially on twitter.
If you're serious about building something, build it. If it's any good, even if incomplete, people will want to join you. It doesn't matter what it is. Really. The guys building the traffic/headline grabbing companies today are just farther along in the process. You can't get there without starting somewhere.
Are you a business guy looking for help building your idea? Outsource it. Pay someone to build it for you. Don't try to "convince" someone else to join your vision and build it for you.
This stuff has to be obvious to 95% of the members on this forum.
Sorry for the rant but this nonsense is getting old...
