I was chatting with Piyush, an old colleague of mine who's kicked off two open source project initiatives on .Net infact using the new Whidbey tools.
It's good to see the no. of open source projects kick up. One of his projects is a
Site Portal (Phase Alpha)
A ready to go site builder which you can use to build a site of more than 100 pages with minimum effort
Infact the alpha build is online with source code (http://groups.msn.com/manasvin/projects.msnw)
Another interesting project which actually kicked me quite a bit is
Forum Alerts (Phase Initiation)
An MSN messenger alert system for users who subscribe to forums & newsgroups.
This is extremely cool as a whole lot of us technology biffs subscribe to various forums. The interesting part is that this idea is going to be built using MSN Alerts SDK. He's currently looking for more people who might want to participate. I think I might contribute to this one. Definitely an interesting idea to pursue :-)
