FON is not new (the company was founded in 2006 by Spanish millionaire Martin Varsavsky) but today was the first time I heard of it. Unknown to me, a new community has been growing world-wide.
The idea is simple: instead of securing your Internet access against other users, you allow them access (through a special FON 'social' wireless router). And they allow you access to theirs. By simply sharing your Internet access at home, you get Internet access everywhere (at least, everywhere near to another 'Fonero'). Hence their motto: Share a little, gain a lot.
The idea is so brilliantly simple, that you wonder why nobody thought of it before. The catch, of course, is that most Internet Service Providers (ISPs) do not allow connection sharing. But with investors like Google and Skype, they seem to be on the right track. And with the bonus of making while helping to build a community, FON will have a strong attraction to many.
