Play for play: blogging for bucks

OJR’s Mark Glazer has a thoughtful article on payment models for bloggers, pay for performance incentives, and pay scales.
Some highlights:
Denton pays bonuses for traffic, but the payouts are banked so not all the upside gets realized for writers.
Calcanis pays a flat rate, reported here at $300-1,000 per month (which jibes with what I’ve heard from some of his writers)
Chris Nolan and Rafat Ali talk about wrangling–and managing–sponsors.
