Matthew is kind enough to publish
the slides of his forthcoming presentation about the five years he spent looking at, using, getting involved and finally making a business with opensource products.
A lot of things that sound very familiar to me, the most surprising to non-involved people being that customer spontaneously come to you when you've made yourself a name and position in the opensource project. Saying "I can provide support" is nothing if you're not involved.
Thanks for this nice wrap-up of five years of sweat!
