I like to regularly check the ranking for the Rolemasterblog. We have a lot going against us: the majority of content is for D&D style games, despite RMU, RM is seen as a legacy system and there are only a handful of people writing new content for Rolemaster or Shadow World.
This month we rank 35th. I think that is very impressive, although I admit to being lost on the methodology used for this ranking system. It certainly gives me hope that there is a dogged interest in RM, and the Rolemasterblog in general.
