I am impressed and very positive about Silverstripe. But i have to convince a lot of other people. And that's why I have the following questions:
1. You can't forecast the future, but what how stable is the Developer community? Is it a product to stay? And why?
2. a) How easy shall Silverstripe integrate with systems like MOODLE, OS COMMERCE etcetera?
b) How easy shall Silverstripe integrate with other online platforms like LinkedIn, Facebook, Delicious etcetera?
Is there a opportunitie to use modules from Drupal? For example I am looking for a newsletter module with campagne option. I believe there is none for Silverstripe (yet). Can I use the one from Drupal? Or other GPL sourches?
I hope you can give me some input so i can survive (and win?) the disscussion so also my coworkers shall pick Silverstripe.
