I am not sure if this is still the case today, but I remember that not too long after the new orthography / grammar rules were passed, two major news publishers announced that they would return to the old rules.

Also, my sister is a linguist, and I can trigger her going on a long rant just by mentioning the Rechtschreibreform. ;-)

(Personally, I think some of the new orthography rules are much simpler and consistent, so I use them. The rest I basically ignore, unless a spellchecker nags me about it.)
