I am a little bit different than you in the numbers--I 100% dislike  
colons, but 99% sure they will never be made optional. That last 1%  
leads me to give it a try here :) I totally agree with you that  
discussing such issues would be a great chance to learn something  
about Python. How many Python users outside this mailing list  
understand the rationale behind colons? I guess it might be a few.  
It's an issue worth thinking.

Colons are also used for slicing. Seem to be overused ...
