A whole new breed of microcompany could be under way - the Independent Web Service Aggregator.
I wonder if this entry on the Google blog has passed through Google's legal department. If it has it's almost an endorsement from Google of quite thorough Google Maps hacking, in that the blogger mentions and even praises the marriage of Craigslist and Google Maps that I've mentioned before.
Let's hope this means that Google reall think this kind of service is a benign use of their data. Considering how eager Yahoo has been lately at beating Google at developer friendliness, this could be a very big deal for the search landscape around us.
