If you haven't heard the Global Lightning Tour will be hitting NYC on 3/27 and 3/28 which you can sign up for here: https://developer.salesforce.com/events/workshops/lightningtour-nyc

This Global Lightning Tour is bringing some of Salesforce's finest employees from product management to town.  The product management team that owns lightning will be coming to our user group to hear YOUR experiences migrating to lightning.  

Be ready to share your successes, your challenges and your concerns with migrating over to the Lightning Experience.  In a few days, we'll be posting a form for you to fill out where we can collect these things and pick a few speakers to present and show these things to Shawna and her team.   Your feedback will be going directly to the product managers.
