I had a conversation with someone who was religiously homophobic on HN recently.
Their mind probably wasn't changed, but having civil discourse about intolerance is important.
I'd much rather see a racist post with thoughtful dissent (which the OP can then read, and is pretty much guaranteed on HN) than for racists to just get excluded, and have no cause to change their mind.
They then go to a more extreme forum, with people who only agree with them. The hate gets amplified instead of dissuaded.
Maybe it's like "low serotonin levels" is to depression. A mechanism through which some effects are expressed, but not the root cause, and only one aspect of the condition.
Woah! I completely and entirely forgot the term "forever frame" existed.
Another term you don't see too often these days is the "holy grail" layout. I definitely remember the days of messing with negative margins and clearfix to get my page layouts to look nice while still working in IE 6 :)
I think you're right that Comet refers more to the JavaScript techniques that came from those "forever frames".. but to me it was all about the streaming HTTP hack at the heart of it.
I guess it's academic now :-)
Regarding holy grail layout and IE6.. so you're telling me you're a masochist!
