Douglas, there are way too many obvious conclusions.
1. The obvious one that you're probably hinting at that's so obvious I won't say it.
2. He still can't find the "modify" button so he artificially increases his postcount (which doesn't really matter anyways, but some morons think it does).
3. You can piss him off even more just by typing long posts.
It's generally the case that long posts say a lot more things than short posts. (An exception would be RPG's "artificial inflation" of posts some time ago.) But look at some of the things you get from long posts. First, maturity. Long, sensible posts make you look like less of an idiot. Second, longer posts add insight to the discussion at hand, from clarifications to new (sometimes opposing viewpoints) to simple overviews. In short, long, sensible posts > short, choppy, stupid, pointless, annoying messages. (Otherwise known as SPAM.)
I mean c'mon. I'm a general anti-spam junkie when it comes to message boards. (And in general too. Even the "food" to an extent.) Sure, I'll joke around at times, but I consider doing something pointless and stupid (including one-liners or two... collections of letters -- I'd hardly say "er" or "lol" are words, but I'm just making an observation) just not worth my effort. If it takes me longer to load the page than it does to type the message, well, See 4.
(Suggestion: Rule 13: If it takes longer to load the page after pressing "Submit" than it does to type what you're saying, See 4.)
So yeah I definitely just pissed the guy off. (EDIT: But my Message Board Theory in a nutshell.)
