Thanks for posting this Ken!
I try to watch the Think Data Thursday webinars that take place about every month. They offer some great advice and have a lot of very proficient Tableau customers share each time. The last one called TDT: Tableau – How Did I Not Know That? - July 30, 2015 was really awesome and I highly recommend it!
Breaking BI is another blog I follow for tips in Tableau. He also has blogs on other tools like Excel and Alteryx.
