Not a proper blog entry, I just want to thank two people who have given me advice to help start this blog. Both of them (fairly obviously) are experienced bloggers...
Can Sönmez, a purple belt who trains at Gracie Barra Bristol and runs a highly analytical blog with reviews of instructionals and dissecting techniques and teaching styles; http://www.slideyfoot.com/
Seymour Yang, a brown belt who trains at Mill Hill Jiu-Jitsu and runs a blog mainly based around his own art, gear reviews and a look at the more humorous aspects of jiu-jitsu; http://meerkat69.blogspot.co.uk/
...and yes, I said I didn't like lower level belts blogging for certain reasons, but these guys don't offer instruction. Meerkatsu doesn't deal with techniques at all and Slideyfoot does it from a student perspective, highlighting differences in approaches between different instructors and instructionals.
So yeah, check them out, they're both cool guys and have a lot of good stuff on their blogs.
