I've reorganized my blog(s) and created subdomains under iljitsch.com for different topics. These are the ones:
blog.iljitsch.com and www.iljitsch.com: all posts
nl.iljitsch.com: all posts in Dutch
en.iljitsch.com: all posts in English
news.iljitsch.com: news and announcements, anything timely
bgp.iljitsch.com: posts about BGP
ipv6.iljitsch.com: posts about IPv6 (or IPv4)
network.iljitsch.com: all posts related to networking, including home networks
home.iljitsch.com: all posts that aren't work-related (but including tech/gadget topics)
photography.iljitsch.com: posts about photography
tech.iljitsch.com: posts about tech topics and gadgets
audio.iljitsch.com: posts that relate to audio
ov.iljitsch.com: posts about public transport
Each of these pages has an RSS feed so you can subscribe if you are so inclined.
Posts will go to all the feeds that are relevant, so there will be duplicates if your RSS reader doesn't handle those.
And don't worry, muada.com isn't going anywhere. I just wanted to make a cleaner separation between different areas of interest.
