Not reactive at all, well put response to mostly confused posts (including my own). I think there was mis-understanding on what was meant by scaling -- web community took it to mean something very different from what you meant. Honestly this befuddled me as well me as well, so I suspected as much -- I didn't think Sparkfun would need to go to horizontal scaling which I am quite confident you'll likely never need (unless you're doing something very wrong).
One way someone else put it, MySQL is great if you're using it as a datastore to build an API layer on top (with relational features being a huge plus as opposed to a K/V store). Postgres, on the other hand, effectively does what an RDBMS was originally meant to do -- it itself acts as that data access API.
Also SparkFun is an awesome company -- the SparkFun Arduino kits on my desk do a lot more than blink lights (though they do that too). Please continue to use run-times may be less trendy but which return responses quickly and using physical hardware too.
