For any entrepreneur starting a web business this is a critical question. If you’re building a web application for consumers you’re probably thinking, “I’ll give it away for free and sell advertising.” So be it. As much as I dislike that model, it’s the de facto one for consumer web apps. For business-to-business web applications, the model should be different. And I’m a strong believer in what the guys at 37Signals espouse, which is very simply, “charge for your web apps.”

Thanks to Tom Markiewicz (via Twitter) I came across On Pricing.

On Pricing is a micro-blogging site (using Tumblr) to grab information about pricing web apps from around the blogosphere. It’s run by Paul Farnell, founder of Litmus, who wrote a great article on pricing web apps awhile ago.

Pricing web apps isn’t easy.
