This “publicly post your intentions to help them happen” thing reminded of a site called GoFuckingDoIt in which you pledge an amount based on a goal, and if you do not succeed they keep the money.
Perhaps we could reinvent it in the form of zaps. Pledge some #zaps towards a short term goal you have and if you don’t show a proof of work, them funds goes somewhere (charity, open source software, someone you admire, etc)
