Ask HN: What unknown technical blogs or sites do you read?
I find Planet blog aggregators a useful and surprisingly unknown resource.  Great way to get a view into the blogs of a whole project community without having to follow a pile of them individually; I recommend following the Planet for any project you regularly use or have a strong interest in.  I personally follow these planets regularly (via a bookmark folder that I open into tabs):Planet Debian: http://planet.debian.org/Planet Freedesktop: http://planet.freedesktop.org/Planet GNOME: http://planet.gnome.org/Kernel Planet: http://planet.kernel.org/Planet Mozilla: http://planet.mozilla.org/
