I have been always interested in Small Business and Point of Interests. In my opinion they are the one that can benefit the most from the internet but very often they have no knowledge, funding or simply time to take care of the internet channel.
So I decided to give my input on a project called Wikipronto that is a online business directory like many others (Yelp, YP, etc..) but the main difference is that you can edit the place, adopt it (you may take care of your favourite cafè or fountain) and in doing so you can enrich the set of data, the images and videos.
Basically you can create, edit and promote your favorite place. Check it out the example I made for the Colosseum in Rome.
