I have always been driven by the idea that computers and to the greater extent the internet should be as transparent as possible to the users. People shouldn't care about what the hot new websites are to meet people with similar interests. In fact I think this is most of the problem why people are becoming more and more disconnected from each other on a personal level. And more and more disconnected from the human experience, of social interaction. There is so much communication that is lost when you cannot see a person face to face, and experience things in the same environment that they do. Wouldn't it be great if you could find and meet new local people with similar interests, hobbies, and ambitions, whatever they maybe. The Internet currently excels at all of this even getting people physically together to meet.
However, this requires a lot of active participation of the person searching and trying to find the right website where everybody of a particular interest meets, and then you need to find somebody locally who is willing to meet up for dinner or a gathering of some kind. This is a lot of work to find people who are interested in the same stuff as you are. And it is no wonder so many people just give up. Now imagine that barrier is removed and finding people with similar interests, hobbies, and ambitions is a passive activity. Where you are automatically alerted to a new person or group in your area that shares your interests, sort of like Google Alerts for real life.
I would really like to start working on this problem with a small group of developers and people that share a similiar passion to physically connect people in a meaningful way with other people that share their interests.
