Separated.

After considering, I separated off-topics (unrelated with Debian) from my blog. Someone may like off-topic, but other one may dislike it.
Now I feed only Debian topics for Planet Debian (http://kmuto.jp/b.cgi/debian/index.rss). You can still see all topics from http://kmuto.jp/b.cgi/index.rss. If your interest is only cooking, please take http://kmuto.jp/b.cgi/cook/index.rss.
BTW, I ate Sushi yesterday :-)
