Great read about killing two birds with one stone: build your reputation AND make some money on the side.
I love this approach, because there is a sincerity involved, which is not often associated with business (at large). Maybe it’s only the fact that online has been heavily influenced by open source and freemium or maybe it’s a case that some business people can still be passionate & sincere about what they’re doing… Irrespective, this is a worthwhile read and a definite if you’re a developer looking for some inspiration.
