Considering the nature of that site it's hardly a random poll... seeing that the site articles are primarly concerning VS6 and VS.Net the sample is not a random sample of all professional developers. David,
I didn't say the site itself was a random poll - what I'm saying is that if you polled nearly 500 professional developers on similar questions, I think directionally you'd see similar results.
Yes, the site has coverage of .NET - they also cover Office, SQL Server, etc.
