I had subscribed to a local newpaper and an article showed up where a govt official was complaining about how most of the historic local budget data was still in paper or pdfs. I found the pdfs and converted them to csv and excel files. Found the contact info of the guy complaining and sent him the data. He was so happy about that, he put me on a mailing list where there were a bunch of serious people talking about local issues. That was the big door opener for me.
Make a local club, teach basics to those who don't understand computing, teach at your local college, develop software that understands we need more user friendly software in the scope of security and privacy.
Bless you.
In my neighborhood there's a neighbours commitee that works on making everything better, there's a local library and a few public squares.
They collect monthly fees from members and vote on the council every three years.
They didn't have a system to keep track of this and sometimes had issues really knowing all their members.
I made them a real simple web app and it helped them a lot, I was already a member and they asked in the members Facebook group if there was a programmer.
