He does use ideas provided by the community though. The shield resistance for example was added based entirely on someone's suggestion (i believe). However, he does keep most things a secret aside for listing a future bug fix from time to time. Heck, when version .730 was released, there was no changelog, and i have yet to see a complete changelog for any version released. Not really complaining though, it does keep the game interesting, but i'd personally like to know exactly what has changed when a new version is released.
