Robert Scoble is the Microsoft-equivalent of Slashdot, in that people follow his links, but don't stick around for the follow-up.
On his main blog, he linked to a question I asked about the affordability of XNA Studio. In 24 hours, that blog entry received 537 hits.
I wrote a follow-up as soon as I found out that I had been linked. In the same 24 hour period, my reply received 29 hits.
Admittedly, this does not include people who read my feed, but it's still rather interesting.
