Not mine, but came across an excellent post by Hristo Pavlov (who unfortunately, no longer works in the SharePoint space).

On a side note, I love his last post:

I am moving away from SharePoint and consulting into serious custom software development and this is my last blog post here. I wish all the best to all of you that remain in the SharePoint world.
