I am currently looking at building an Open Source People Intelligence Application (Fancy Word for a phone book) for my church.
It'll basically be a database system where you can view info on a person and automate actions like send a "facebook message to these people on this date", "Generate a consent form for this person's parents" kinda thing..
Let me give you some background..
I've been working in .NET and MSSQLfor the last year and a half (Building small data apps for business) and I think I'm starting to get pretty good at it.
My question is now I'm thinking of open sourcing this project should I plough on with ASP.NET or use something Open Source like PHP (Also open to Python although the syntax looks bizarre, or rails, grails, practically anything apart from Lotus Domino =P)
I am a fairly quick learner but am studying for a Microsoft Exam at the end of the year and have a lot of projects at work at the moment..
Most people don't want a gritty my "my language is better than yours" debate but I Love them so go ahead!!
It needs to be secure though cause it's real people's data!
