Yea I'm not so keen on that sort of response to something people find so anti-fun. A developer should not be acting like the general population, a little professionalism goes a long way.
I find it endearing.
It's nice to know that devs are humans just like us, full of imperfection and potential.
That being said, I don't think blobbing is anywhere near a 'problem.' I can't find a way it necessarily reduces depth, in fact in the total absence of 'blobbing' there would be no such thing as force concentration ever, and all troops would be spread out everywhere.
This probably paints his response in my eyes, though. I'd like to think I have a high default risibility.
