An interesting take on the topic. I would tend to agree with it. I've always maintained that it takes a certain something to be a programmer. The specific language is less important if you have a "programmer's mind". I've worked with a bunch of different languages. Once you get over the varied learning curve of the exact syntax and structure, it really just leaves you with the general logic and planning and all the stuff that any app is going to require regardless of the language. These aspects are not as easily learned as things like "always (or never) terminate with a semi-colon" or "white space matters".

But I also struggle a fair amount with remembering all the rules... and exceptions to those rules... and exceptions to those exceptions... when it come to American English. Sometimes I actually have to pause and mentally recite the rules for "its vs. it's" and things like that. I think that comes from there not being a strict compiler for the that. The reader is going to be more forgiving in the sense that even if you misuse its when you should use it's, the reader is going to to understand your overall meaning. Most won't correct you because it doesn't really matter to them. Think about the butchered language that gets used on Twitter to get things into 140 chars. It would be nearly impossible to write an interpreter that would take most tweets and rewrite them in proper English. You have too many variations to make that work. But the reader will probably have less trouble with it.
