Don't forget acronyms, of which we have many. And capitals are an important visual cue to indicate the start of a new sentence. On the self-submission question - I have no problem with it, if it's interesting, and this one is, if flawed. What I don't like is when people repeatedly submit their own blog posts here, every single one it seems like sometimes - I wish that could be programmatically blocked somehow.
