I love the Favathons! It sure has put lots of action to my store. I also like scheduling my tweets and Pinterest posts to more then one Pinterest board. It's great that I can do sales and social media schedules in one place instead of using EtsyOnSale and AroundIO. It is a one stop do it all!
I like the keyword tool, It really puts things in perspective. I love the ability to see what is the most popular in my shop via views and purchases. The sort function is awesome! I just clicked on the analytics reporting page for the first time today and it seems like there is a lot of meaty information there!
