At the risk of being told I "only post others' opinions," I found both of these articles interesting. If I post others' articles it is because I (for the most part) like what they have to say and feel that it is unnecessary to reinvent the wheel by restating what is well-put, even the parts I might not fully agree with. I don't always agree 100% with the authors of my posts, but if I feel there is enough of an agreement to overlook the parts I don't agree with, I will generally post the whole thing.
I thought these were both good. Read at your own risk.
