I would imagine it depends heavily on your email load. I get plenty of email, but the majority of it is automated, so with my gmail fitlers, I have only 2-3 per day that I actually need to read.

OP, on the other hand, is the founder of Grouper, and presumably gets dozens or hundreds of emails from real people requesting his time, input, or other resources. As such, there's significantly more effort involved in determining that a given email isn't worth responding to.

I don't know what your situation is, but I would imagine OP has significantly more real-person mail than the average HN poster.

Minor nitpick but the page shows he's the founder of Grouper, not Groupon.

Whoops, thanks. Updated. I was thinking of Grouper when I typed this, anyway.
