Simply put, I counted 6 people reporting this here (I am one). My attempt to estimate how many people read this: X HN daily actives, each looks at Y threads a day (random out of 30 they see), one in Z posts to the thread.

Quick check with Alexa gave me something on the order of 2 million for X, that seems really high to me, let's say X=100k (even this seems very generous). Y and Z are pretty tricky, using a gut guess of Y = 5 and Z = 10:

6 * Z / ((Y * X) / 30 ) = (6 * Z * 30) / (X * Y) = 6 * 10 * 30 / (100000 * 5) = 0.0036 = 0.36%

0.36% of the HN audience. Very back-of-the-envelope.
