Now my "community" is a vague term here, but there's no size limit. Big or small, I'm seeking to donate my time and genuinely help people. I say community, because I imagine local platforms are some of the least developed for. Hard to monetize so it doesn't get attention.

My first thought is a classical problem I feel affects everyone. Information about laws, politicians, etc. I would write/install a platform to manage data pertaining to my local offices, laws, etc. This also involves quite the time donation on my part, to obtain information, keep it up to date, moderate edits, etc.

With all that said, perhaps you have some ideas on how best to help the people around you with developer skillsets?

Thanks to any replies :)

edit: Also, ideas on recouping or avoiding costs would be appreciated as well. Ie, using perhaps a free CDN to aggressively cache content and reduce billing, etc.
