Kickstart, a social network for college students, what facebook started out as...

<<Yahoo’s advanced products group, led by Scott Gatz, is launching a new service this evening called Kickstart.

While immediate analogies will be drawn to Facebook, the service is actually much more like LinkedIn in that it connects students and alumni at specific colleges and universities and helps them connect on a professional level. Alumni can help students get jobs (or can find good students to fill spots at whatever company they work at), and students can reach out to others to help jumpstart their professional career. >>

And the second, Fireeagle,a platform...

<<Yahoo isn’t just announcing Kickstart this evening. Salim Ismail’s Brickhouse is announcing a very useful new platform service tonight tentatively called FireEagle, which is currently in closed alpha testing. The team is working on the launch name and final launch date now – it’s expected to be open later this month.

FireEagle, which is built entirely on Ruby on Rails, was originally inspired by Yahoo’s ZoneTag research product. It is a platform for controlling people’s location information. Tell it (directly or via a third party application built on FireEagle’s APIs) where you are (give it specific lat/long, or a city name, or a zip code, etc.) and it will note your location. Alternatively, users with GPS phones (or other GPS device) could set it to periodically update FireEagle with geo information. >>

Kickstart sounds cool but Fireeagle sounds a little too big brother for me.

Big bro? are you refering to Yahoo's produc or OpenSocial here? talk about Big bro..
