IBM Lotus Notes Domino as a Social Media Platform

Currently I am evaluating to see if Domino will be successful in delivering as a social media platform. I need to select a platform that is interactive with users and rich in social media such as blog feeds, youtube videos, tweets, etc. I would love to hear some feedback from folks that have successfully implemented Domino as a viable solution for this purpose. I would also love to hear about what are some of the more popular platforms people are currently using? Please leave your comments below.
