If you weren't able to get to Las Vegas for Lync Conference 2014, you can now see all the content online at Microsoft's Channel 9 page.
I did two very well attended sessions on Enterprise Voice Best Practices. You can see both of them online, if you're so inclined. I recommend checking out the second one on Day 3 at 9am (BEST301-R). For whatever reason, MS didn't have my most up-to-date slide deck for my first run-through, and there were technical difficulties which meant I almost wasn't able to demonstrate the Lync Optimizer.
And if you're going to be at TechEd 2014 in Houston on May 12-15, come see me perform the same session on Tuesday, May 13 at 10:15 AM (OFC-B339)
