I run the local meetup group for D&D and although I know that a lot of those guys are starting up 4e games or at least running trial adventures, I wanted to be sure I got people looking for Pathfinder as well. So I started a new meetup with "Pathfinder" in the name. When people do searches for RPG meetups, they also find Pathfinder and become intrigued.
I'd encourage others to do the same when advertising their games.
