No credit belongs to the person who send out this misleading email:
"Free eBook: SQL Server Execution Plans, Second Edition"
And you can quote me on that one!
My time is my life / my life is my time. If you waste my time you are to a degree committing murder. Albeit by the salami (slice) method. By sending out an email promising something that is not available (yet) is at best being misleading. In my youth we used to call this vapour-ware or cripple ware. Not the real deal but sexy enough to make you look. I can only speak for myself but I am seriously annoyed.
You are under absolutely NO obligation to provide ANYTHING for FREE. Not even my lunch or the time of day. But you are under obligation to be truthful or at least discourage others not to be misleading your behalf.
I feel mislead and I'm cross. Am I alone I wonder.
