That said I am thoroughly fed up with the number of U-turns the authorities performed handling German orthography.
You take the words right out of my mouth
Still don't know - and now no longer care - if ß is in or out
I'm not entirely sure what you mean, but the new ß rule is not that difficult (the old one wasn't, either, but I'd argue that the new one is even easier ... but well, most people don't get it either way).
That's a matter of choice, actually ... and it's not too different from the old rule, where it was mainly a matter of choice as well. I mean, the only occasion when you ever capitalise Du is in birthday cards. Few of them will win a literature prize, anyway.
A lot of the new rules work on an "anything goes" base ... but then, some rules surprisingly don't. You can go "ich habe Recht" and "ich habe recht", but you can only go "es tut mir leid" (even though, at some stage, "es tut mir Leid" was allowed as well) ... I have no idea why they didn't just go for universal decapitalisation at all when they set out to reform the spelling, anyway.
der gefangene floh is not really a convinving counter argument for me.
