About comments and the "I am..." stuff etc. - I don't really care that much about how a comment is written as long as there IS a comment. And personally I find it much more important for people writing comments to remember the distinction between the class and the instance.

I always get upset when I hear people blurring the lines - it really doesn't help the newbies/beginners since that is one of the things they have the most problems with (in OOP, not specifically in Smalltalk).
