Huzzah to McCracken! And that little detail is why I've rejected weekly offers to "endorse" software on my little site. Someone does the Microsoft thing every other day of sending me a request for ads or they'll send the big Pro version license key with a download link. I reject them because I want to go through the same process any user would when evaluating and buying their software. I get to find out how crippled their trial version is, check out the version I could afford first, and so on.
That way if I don't like it, I can return some initial feedback, but it doesn't make the list. And I'm free never to feel obligated. Web 2.0 got real nasty this week over the sheer LACK of integrity of DIGG regarding the HD-DVD hex key.
