Traffic on the RPG site Stack Exchange has leveled off. But there is a steady stream of questions and answers on a variety of topics. I realize that many of you are not keen on the whole being able to edit other people stuff. But the moderators are up and running (I am one of them) and we dealt with a few situations already. So you may want to stop by and give it another try. Plus there are now history features that allow you see to see the edits being made and tools to manage those edits.
In addition they added a chat room to the site. The software behind it is pretty good in my opinion. I like how you can pop in and see the previous conversation as far back as you want to go. You can set up rooms of your own with the tools there. It is a new feature so feedback is appreciated.
Note that the questions are dominated by D&D 4e which can be off-putting to many readers of this blog. However questions about other RPGs have been answered and unlike system centric these questions tend not to be crusted with opinions proponents of other systems. The tag system allows you to filter out all the questions you don't want to see. And one good thing about how Stack Exchange works is that people put a lot work into making sure the tags for questions are accurate.
