'Guu kan' 偶感 (or 'Guukan') is a Japanese word meaning 'Random Thoughts'. Just a place to post any kind of topic (except web development related, which is what my Web Developer Blog is for). I also thought of 'Futokutei' 不特定 (unspecified / random / indefinite), but spelling it is harder (I have to keep double checking the spelling). 'Randamu' ランダム was also an option, but it is close to the English word (which could also be misspelled).
