I started writing a discussion of "What Makes a Good Tool for 'Mobile Civic and Social Innovation' " but it just kept getting longer and longer to the point that even I'd had enough, let alone anyone else reading it.
So here is the short version (which has turned out to be useful and surprising to put down like this):
1: works on any mobile phone, straight away
2: no registration
3: post but not pre moderation (you mostly won't need either)
4: partnerships (a way to get your call to action out to people)
5: a well worded call to action
6: examples for participants to follow
7: an awareness of the context: who is here? what do they want?
8: an archive that values the responses and keeps them in context
9: access to the archive from any mobile phone, straight away
The problem with putting these 9 points down like this though, is that they are based on nearly 10 years of experimenting, succeeding and failing to create civic engagement through mobile phones, and so even if (when) I've got them wrong, I know inside-out what all my reasons for, and discussions about, each of the points would be.
But it might not be so clear to anyone else what they mean or why?
So, questions, comments and doubts are very welcome.
