My teacher used to argue that modern English would have been better off taking the Chinese writing system rather than the Roman one. The way it works now you have all the drawbacks (i.e. you need to memorise a whole lot of pronunciation) but none of the benefit (i.e. faster reading speeds, more compact representation).
Rather than going to that extreme, English spelling could be made easier. My native language is Dutch. For Dutch there are spelling reforms every so many years. English is still using Shakespeare's spelling, I think. The advantage of spelling reforms is that spelling can stay much closer to how a word is pronounced, and that it's much more standardized. The disadvantage is that older texts become hard to read much so…
Is that so? I'm pretty sure everybody pronounces pannenkoek as pannekoek.
Don't get me started on conjugation of loanwords such as "gedeleteted" (I hope I got that one right)
