A talk about how to determine the right tool for the job.

Or a talk about the appropriate use cases for certain new features and examples of (common?) incorrect application of certain new features.

It is not always a matter of knowing all the new features, but to be able to determine whether they are applicable to the problem at hand.

What we often see is that features can get overused because they make the coding easy (e.g. table variables, CTEs) but they may have unforseen consequences.

What are some newer examples of this kind of thing?
