IBM Lotus Notes Domino as a Social Media Platform

Currently I am evaluating to see if IBM Lotus Domino will be a robust platform for social media delivery. I need to select a platform that will be interactive with users and provide a rich social experience to the user with the commonly used features such as: RSS feeds, YouTube videos, Facebook, Tweets, etc.

I would love to hear some feedback from anyone that has successfully implemented IBM Lotus Domino as a social platform. What were some of your challenges and what worked well/success stories?

Do you suggest any popular platforms organizations are currently using for businesses? Please leave your comments below.
