I hate the term 'giving back'. What has someone given you that you should give back?
Why not just say, 'give'?
I feel that in the software community we're standing on the shoulders of generous giants who have coded and open sourced so much of our tech stacks; written guides, tutorials, and tests; answered our questions in forums and chats. Granted, this seems like a more entrepreneur centric project, but I'm pretty sure that we're all benefiting from the works of entrepreneurs anyways.
