Richard Pope in the comments: "I'm having the same dilemma with StreetWire.org, which is a UK project along the lines of EveryBlock. I've not been able to get funding from anyone, and can't afford to keep working on it myself for much longer (I've done 6 months with it feeding my credit card). I could open source it and maybe get more help, but that might cut of any chances of getting funding later. "
