(this might be better suited as a community wiki, can one of the mods edit it please?)
Info : I have one main blog, where I discuss IT stuff like programming, android, Java etc which compensates my day job nicely (Java developer).
I want to start blogging about other, non related interests (such as karate, fitness, languages etc).
Question : Would it be best suited to setup a second installation of WordPress for these, or should I just keep one installation and separate using categories? What are the pros/cons of doing this?
