If I was in control of WPTavern I would put it up for sale as quick I can, make some quick money, buy a real Tavern and sell beer. Then I start selling premium themes - thats were the money is. No, not really.

But seriously I would create more "how to" articles, tutorials, and case studies about how WordPress is being used in various industries, showcasing examples and the processes of how people use WordPress to create a website. The plugins used, custom hacks etc.

You have already put in a lot of work to built a great PR5 site which can easily be taken to the next level.
