What are the disadvantages of using Ruby on Rails versus ASP.NET MVC to build a social website?
I ask specifically what the disadvantages are because it's easy to find and read about the advantages of using RoR instead of ASP.NET MVC.  But I'd really like to get an insiders opinion on some the disadvantages so I have a better idea of what to expect when I begin building a social website using RoR.

Thanks so much in advance for your wisdom!
