I first wrote about this in early 2005: Having developer blogs on people.netfilter.org. Unfortunately I never finished that project so far. I'm not really a web guy at all, so doing stuff related to (X)HTML and CSS always gives me the creeps. Why can't we just have a technically skilled web master volunteer for netfilter.org? *sigh*
Every netfilter developer with an account on people.netfilter.org can easily set up a blog, just by putting blog articles into ~/weblog/.
