20 something males who already nerdy, geeky, and have similar sense of humor to me.

You can add 20-30-something females that are nerdy, geeky and probably have a similar sense of humour to you ;)

I have a minimum of two data points for that demographic ;)

That being said - I agree it should not be our only avenue or our only target demographic. But even if we expand readership/membership in just the geek demographic we can considerably improve our numbers.
