Can you expand on why you consider Rails to have doomed them, and why NodeJS would be better? I'm not particularly familiar with either technology (besides reading about them here on HN), but it's my understanding that Rails powers some very big websites, like Hulu and Github.

That said, there's already a working Twitter-like distributed network. I hard my own StatusNet node running on my personal server and getting messages from people on Identi.ca, until I realized that I found the idea of the platform interesting, but not the platform itself (nor Twitter, for that matter). The fact that half the accounts were abandoned didn't help either.

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.
