Agreed. I wrote a couple-page cheat sheet on Objective C, and since I've made a twice-yearly ritual out of forgetting Objective C, it's come in handy. Repeatedly.

If you ever have time or inclination to share it, I could use a good cheat sheet. The closest I have now is "Objective C for C++ programmers", but it's not short enough to be a useful cheat sheet.
