The goal would be to have travel/training blogs across all the main disciplines and countries. If you are training in Japan and writing a blog that would be fantastic then.
I decided to focus on Brazil and Thailand (BJJ and Muay Thai) as these are the most popular options. I'll have my own blog going up in a few months in Thailand, already got a solid BJJ blog going on, and another BJJ blog from a friend later in the year.
The reason why I want multiple blogs is because this niche of blogging (training/traveling) is not a very permanent lifestyle for most people. It is painful to get sucked into a really good blog and then someone stops training/updating or goes back home.
