Other than the cost and the admin factors building, deploying and debugging/troubleshooting web applications in ASP.NET environment simply rocks! Not to mention the IIS sweetness and scalability models. I have a facebook application (http://www.facebook.com/apps/application.php?id=5595659604 http://www.facebook.com/apps/application.php?id=5595659604) that I built using the LAMP stack, something quick and dirty . I like the LAMP stack and have nothing against RoR but be prepared to spend a lot of engineering resources in scaling these. Case in point try debugging a web server crash in your favorite RoR web server vs ASP.NET/IIS environment.
