I teach composition for a living (most semesters anyway--right now I'm a copy editor at an academic journal). So I know some things about punctuation. Here's the most important thing: the purpose of punctuation, spelling, and other conventions of usage is to get a specific meaning across in the way you want to get it across, to a particular audience. If this means using sentence fragments, starting sentences with coordinating conjunctions, throwing in ellipses to indicate pauses... then it's effective.
Back to the OP: My gripe with all the INTERNET SHOUTING!!!1! of the zzzOMG! OBAMAR IS A TERRIST!!1!! variety is that it communicates so little, and what it does communicate is often against the intentions of the author. It convinces no one who is not already convinced.
One thing I can not remember since my mother corrected me a few years ago (she's basically an english teacher) was about the use of quotations. I have asked her 3x now and can't seem to remember, but I think there is one exception to the punctuation-goes-inside-quotes rule (e.g. "this," and "this.") Whenever I Google it, I always find conflicting opinions. It seems logical that if you are talking about a list of items, the comma would go outside the quotes (e.g. "a", "b", "c", "d", and finally "e"), but I'm fairly certain it should not, since I am pretty sure I quite clearly recall that being the specific mind-boggling truth I was forced to accept several years ago (in other words, in America, at least, I believe it is supposed to look like this: "a," "b," "c," "d," and finally "e."
But, there are other occasions where perhaps the punctuation comes after
the quotation mark, I think; for example, if you were to write someone might think the "e" should always come after the "i", but that is not always the case, as in the case of the word "weird."
Following the convention of punctuation-inside-quotation, the last half of that last sentence should be written like so: …for example, if you were to write
someone might think the "e" should always come after the "i,"
but that is not always the case, as in the case of the word "weird." …But, I'm fairly certain that form is incorrect. Now, about that last ellipsis: should it have come at the end of the previous sentence, like so: "weird…" …or did I do it correctly? What about that last time?
How about that weird problem with using italics and then using italics within italics so that you have to revert back to regular non-italics as I did above? Stephen King does that all the time. I think it can get awfully confusing.
By the way, nothing irks me more than an improper ellipsis, so while we're on the subject, it's not "three dots" or "four dots" (or more), it's an ellipsis! Three dots looks like this: ... and for dots looks like this: .... but an ellipses looks like this: … Please note the kerning between the so-called "dots" as the lower class
may refer to them. Harrumph! It is an altogether distinct mark with it's own keyboard equivalent ("command ;" on a Mac). Now, then, I am off to stir a great big pot of manure I like to keep warm on the stove.
