Let me tell you a short story!
Once uppon a time a community member has come up with an idea. The rest of the community members have started to vote up his idea and a developer have seen this on FB and then a he has picked up that idea and he has started working on it!
After two days the developer was able to integrate something into his beloved 3d modeling software and this has gave him a great push that crystallized out his next project.
