Social networking websites have become an accepted (and hugely popular) way to meet an interact with people. With the massive success of MySpace, the trend will surely grow, but rather than general interest networks, the more interesting area to keep an eye on may be smaller niche networks, tightly focused around specific interests.
One such effort is Edmunds.com's new carspace.com (maybe not the most original name), built for users who wish to interact with others sharing a passion for cars. In these kinds of more narrowly defined spaces, brands can explore various marketing opportunities, provided that they contribute something relevant and valuable to participants. Honda is already onboard with carspace, so it will be interested to see what they do in this role.
