The 411 on those 404s:
Due to bureaucratic bungling and our own stupidity, we have temporarily lost control of our domain. (Sordid details.) A List Apart is currently being served at alistapart.zeldman.com. Kindly update your bookmarks and spread the word while we sort out the DNS mess.
We have not yet transferred the back end, so the mailing list and search forms don’t work.
They will soon.
