Hi Tom. While I feel what you're saying, at the same time I think sometimes we "seasoned" folks forget how we got here. For some people just entering this arena, who may not yet be aware of the golden separation of concerns/semanticially correct models, it may just be that they need to hear it in order to move through that natural progression... and if we stop actively ranting about it then we're just leaving it to chance for them to stumble upon an article on the subject (not that there is any shortage of those)... whereas we can keep up the good fight and help out the noobs by pointing out these methods, even though that may come across as being pedantic at times... just some thoughts from the flip side I guess.

There is nothing wrong with doing it the way he did.  It's faster to
code when coding by hand.  It will respond to events as soon as it's
displayed rather than after the entire page has loaded. Etc., etc.

Yes, you are correct that current practice is to separate behavior
from semantic meaning and meta-data.  Yes, coding in a consistent
style through multiple projects makes code easier to revisit. Yes,
all of the (blee/lead)ding edge standards go so far as to suggest all
js be in a separate file. In all of this, we forget that the "old
ways" still work. You see, you took 5 lines to accomplish what he did
with an inline handler.

Sometimes quick and dirty is just fine (especially with an older
DOCTYPE). Let's not be too zealous about it.
