Rails is geared for CRUD apps, not messaging. Whereas NodeJS is built for messaging. Picking the wrong technology stack for what needs to be a messaging protocol that resembles SMTP definitely contributed to Diaspora's lack of adoption, but certainly wasn't the only reason. StatusNet actually sounds kinda good. Why isn't it more popular? I'm not sure, perhaps people need something more than just a replacement for Twitter. I think something that will eventually become successful will be some sort of multi-use low-level protocol that handles many types of "social communications", for example: Twitter + WordPress + Private IM + Voice Message.
