I've been on the Ecosystem team for just over half a year now. I don't know how many times I've been told, "PLKs suck", "PLKs are hard", "Why do you need a PLK?".
I even had a customer come up to me at Tech Ed lecturing me how hard it is to get PLKs. :)
Anthony has been on a mission to kill PLKs but in the interim, he's helped make getting PLKs a lot easier. Check out: http://msdn.microsoft.com/en-us/vsx/cc655795.aspx.
No more waiting for an email with your PLK! It's all automated now! woo hoo!
