Check out the posts by Gayle Lakkmann on quora[0] related to common English mistakes (you might have to register, but it sounds like almost exactly what you are looking for). It is focused a bit more on mistakes common to those from India, but it is worth checking out. Your English is very good, and I have no trouble following your sentences. Through your use of commas, your writing actually "flows" better than many native writers whose work I read.

Also, I apologize profusely for some of our ridiculous grammatical rules. I'm a native speaker, so I don't think much of it, but I'm amazed at how poor some of the "rules" are.
