For the most part, and leaving aside some tool-making or data-checking programming, I think it is far more relaxing to add data to the world than to add more systems-for-working-with-data. Contributing to Wikisource, Openstreetmap, Commons, even Flickr and Reddit, will further the cause (what ’cause’?) more than building some new system for cataloguing photos or conducting conversations.
So take photos, draw maps, write blog posts, explore the world and record what you see. Don’t devise the means to do these things — we already have the means, and have had for a rather long time. Better to get on and do it, I think. The means won’t be perfectly what you’d prefer, but then they never will be (even after you’ve built the system that’s perfectly exactly what you want).
If you see what I mean?
Anyway, I’m only saying this because I’m going to be away from regular coding for a few months from next week, so shall be focussing on Doing more than Building. And I can’t wait!
