I think I have come up with an idea for an open source project using ASP.Net. We now have an almost infinite number of ways to communicate using the internet, with more coming online every day. The problem is that if you want to create an event you need to use at least the following servers
1. Facebook (must have)
2. Twitter (must have)
3. Google Calendar (nice to have)
4. Flickr (maybe have)
5. Blog (maybe have)
6. Google Wave (must have in the future)
In fact this may work best as a Google Wave Gadget, now to discuss the idea with the person I have teamed up with to see if he likes the idea too.
