Agile in action - Lesson I've learned from business is their agile practice is, basically, keeping everything in email, i.e., Microsoft Outlook; design and functional specs in Microsoft Words; data in Microsoft Excel, and attach the doco and spreadsheet into the email ...
Agile != Lazyness
Being lazy by taking short cuts and implementing bad practice is not being 'agile'.
Email and the Microsoft Words and Excel in its attachment is one dimension and a disorganised way keeping the information. The least efficient or no penetration.
Email is dead in next few years is on my wish list. There are a lot better way connect people to communicate than email, for example G+.
So Google, watch my mouth and listen to me carefully. I really want you kill Gmail in your thing to do next :-D
This produces mixed results depending on what email address you're sending to, but it's a good start :-)
