The truth of the matter, is there should prolly be a disclaimer on the entire site, citing that the site provides solutions or less than ideal versions of such. That good programming practice should be adhered to. That questions are at best, on programs where all of the code is given. Most of the time it's not true. You will get things such as sniplets and why this sniplet does or doesn't do what it does. Sometimes it's enough, sometimes it's not.

Then the posters meet, as they always have done on this site. Someone wants to know something, there's banter and what not. But rarely, is it the validity of the HTML but the functionality in perl, or what have you, they are trying to achieve. If I wished to pick appart everything a person wrote, and what I wrote, and explain why things are done the way they are, I'd sit here for days, and then argue to death with zealots who claim my way is wrong, when it's really not right for them. Or I will make mistakes and mispeel stuff. My American is terrible.

Anyway, you have the ideal which you present, that we in ernest strive for, then you have the worst nodes, usually bad code or flames.

But as I use my invalid html to post this, with my unmatched P tag, and you read this post, from start to end, you walk away with something. Either you agree, disagree, learn or are enforced in new ideas, or counter example (via disagreement) or I've stolen 5 minutes of your life on your question, code related or not. It's life. You take the good, you take the the bad, you take them both, and need to sort it out what's what and where it goes in your mental files.
