Well, I'm going to be serious here at first, and then ease into snarkiness. That thread taught me some valuable lessons.
1) Online, people can really draw the conclusion they are intellectually superior to other people based on one problem, one interaction, one event. I had never actually considered this before. And ironically, what they are doing is drawing a conclusion based on minimal data from one math problem, which is itself antithetical to the entire notion of probability. The people who do this are entwined in a kind of paradox, which I find cute, funny, and absurd.
2) I have gone 57 years under-appreciating the importance of tense when discussing real life events and the math associated with them. When people change tenses in "person-of-interest" interviews, it is a red flag signaling obfuscation. I have known that for years, but needed to be reminded of it by a law enforcement friend. I had not considered that changing tenses in writing may also be purposeful and a tool to create confusion. Now I am alert for it.
3) The ubiquity of anonymity in online forums continues to baffle me. If the trend is for Facebook and Twitter and such to personalize interactions, why would anyone seek out anonymous interactions? Academic journals don't publish anonymous papers. Would some of the WoVers really be as obnoxious in person as when online? I have a hard time believing that.
4) I realize that many civilians (as one WoVer said in reference to the regulars here) are math-blind to some extent. I had never realized how language-blind some of the math club people appear. It is startling to see people not accept that a question often misinterpreted is a bad question. It doesn't matter how clear and concise it seems to YOU. If many or most people misinterpet it, it is by definition a bad question. There is a math-blind aspect to this that is interesting. The fact that YOU get it is anecdotal evidence that the question is okay. The fact others do not get it should hold more weight in your mind if you're truly probability-oriented.
Anyway, I seem to have left out anything snarky, but I'll work on that. This has been a valuable exercise and experience.
