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?

My list is still too long. ive done a couple SQLSaturdays and quite enjoyed them, and i always learn a lot of new things, but their other effect is always to remind me how much about SQL server I still DON'T know.

As it pertains to my current job, top priority is learning all the SSAS/SSIS I can, especially best practices around team development in those areas.

But on a personal level, I want to sharpen my query/programmability optimization skills. I know a lot (much of it from reading and participating here) about tricks on writing better queries and such, but still a newb when it comes to actually breaking down execution plans, and analyzing performance of queries.

Very cool. I'll start with a bit of a play on words. "Just because you CAN do something in T-SQL, doesn't mean you SHOULDN'T." :-P

POWERSHELL.

Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.

Our budget at work is very tight. No money for any conferences nor any training. The possibilities of lay offs are very real. Last year we had our first SQL Saturday; the only training I'll get this year is another SQL Saturday, if we have one, plus what I can learn online.

Very similar to my mantra (different meaning of course): "Just because you CAN do something in T-SQL, doesn't mean it's a good idea!"

I have to disagree with you on Powershell though.
Because of issues with SCOM, I created a whole suite of powershell scripts for my monitoring and admin needs.
Allowed me to have a single set of scripts that I run from one place, and all I have to do when i set up a new server is add it to my server list tables and set up the login that runs the scripts.

Now I am even monitoring AWS MySQL instances with my scripts.

This is very similar to what i used to do with shell and perl in my previous life as a Sybase DBA.

The one gotcha I have come across with powershell is memory issues, particularly related with how it reads files.

I'm not suggesting that Powershell is a bad thing. Even I use it.

My response was because someone asked if something else had been abused like Recursive CTEs, Cursors, CLR, etc and the answer is "Yes"... like any shiney new object in SQL Server, Powershell has been seriously abused/misused. Most of the people that are doing the abusing seem to be those who know how to program and not much about SQL Server. There are a couple that do know SQL Server quite well but insist on doing simple things using Powershell just because they can.
