I think the OP's intent was slightly misunderstood and likewise I understand the backlash. I had to re-read the OP myself.
That being said, many replied with both vitriolic condescension and posturing. From some I expected this; from others I was truly disappointed.
Posts like this (if not trolls) should be seen as an opportunity to discuss, educate, and maybe illuminate. P-F has no shortage of intelligent, articulate, and experienced folks to do so (for now).
If the idea of rehashing legacy concepts or previously-but-not-currently accurate information is too unappealing, it is too easy to simply move on to the next thread and not post. I do this frequently on P-F and yes, I know I didn't always do this. I'm trying - real hard - to be a more productive member of the P-F community.
Based on current and emergent events, reveling in the eating of our own may be a highly detrimental course of action. This type of thread/behavior can and does chase away those in need of education and those who can provide it. I recommended P-F to people as a "professional source of information." I'd be embarrassed if someone I told to come here saw this thread, and not because of the OP.
I'll close by saying this: don't take this personally, anyone. I'm not attacking but I am making what I think are necessary observations of the overall thread's vibe. I'd like to see the entire forum - and all of us - just be better. @
