Hugo reported earlier this week that you couldn’t comment or visit old posts on this website. I did some investigating and have fixed the problem. So now you can browse the old stuff if you really want, and leave me comments ;)
For the technical people: I changed server, and with the server change came a uname change (skroon to kroon). Things didn’t break for general ~skroon links, since they were fixed by rewrite rules, but wordpress’s rewrite rules weren’t playing nice with the server-wide ones.
