I wish I had been able to convince the guys to use a relational DB from the beginning instead of Mongo. Turns out a social network is full of relational data - but my buddies were too excited by new tech, and made a decision based on “cool”ness that hurt themselves in the long run.

However, it’s still impressive what four guys at the end of their college careers were able to build with no professional experience whatsoever. (Though it took me a full week to convince them to use a framework, Rails, instead of hand-rolling everything around a custom EventMachine loop... The loop never even worked, but it was “cool”. Give me boring and powerful any day.)

I think the biggest missed opportunity here was that an advisor of my own suggested to me that they really should leverage SMTP and build a better experience on top of that. An advanced mail client with social network-style features and presentation, and an obfuscation of the “pod” concept (do users really care which one you’re on?) could have been a smash hit and could have had fallback design to allow non-network-members to still be included as leaf modes in the Diaspora social graph. I couldn’t wrap my head around any of this at the time, so they never heard even a whisper of the idea. My bad!
