So today I got an invite for microsoft's popfly . Popfly seems to be msfts take on letting users create mashups, websites , communities etc without typing in a single line of code and is powered by silverlight. The key word here being "user" which means anyone can create a mashup without knowing how things work behind the scenes.
The site is in alpha, and there are definitely some issues that I have come across. But the UI is amazing, it works with firefox ( big plus ! ).
I will be messing around with this and see what mashups I can come up with. Please feel free to add me as a friend ( http://www.popfly.ms/users/Kashif ) and I will post invites for users as soon as I get them :)
