Let me know if you can think of any other pre-2009 old school gameblogs.

I don't know why I am compelled to undertake these tedious blogometric exercises. I think it reflects some sort of personality disorder I have.

Here's a ranked list of 245 old schoolish roleplaying blogs ranked by the number of followers they gained between April 1st and June 6th. I rank blogs using this system - as opposed to raw follower number - in order to determine which blogs are "hottest" without being biased by how long a blog has been around. My main motivation for making this list is to highlight the blogs that are currently attracting the most reader attention regardless of the blogs' age. Out of respect, I DO NOT list blogs with zero or negative growth.

My usual blogometric caveats apply: (1) This list only has blogger.com blogs because follower numbers are not publicly available for WordPress blogs. (2) Yes, I know some blogs are missing. If I am following your RPG blog as of today it should be in the next ranking. If your blog is not on my list and you want to be included, please email me the link through my profile. If I made a mistake please let me know - I am not consciously trying to exclude anyone.

Tied for first we have Grognardia and newcomer Gaia Gamma! I assume that I don't need to describe Grognardia to anyone - it's consistently one of the biggest, fastest growing, and most influential blogs in town. Gaia Gamma, on the other hand, is a new blog focused primarily on creative content related to propietor Thomas Biskup's post-apocalyptic RPG design. Fans of games like Gamma World and Metamorphosis Alpha should love this blog. Great great stuff!

In second place we have another newcomer: Grognardling! This blog is all about straight up old school D&D and is remarkable because it is one of the few blogs written by a younger gamer who didn't actually grow up playing the game.

In third place is Strange Magic, one of a very small number of blogs focusing on Weird West gaming. This blog features frequent well written posts and lots of cool YouTube links. Nice work, Stuart!

In fourth and fifth place we have the venerable and widely-read blogs Playing D&D With Porn Stars and LotFP: RPG, respectively, which, like Grognardia, need no introduction.

Here's the whole list. You can link to any blog by clicking on its name:
