The fact that your question was not narrowly answered
in the format you asked it does not mean that it was not
taken seriously.

Nobody is ignoring it; they're asking why you need
to screen out other browsers.

Apparently not, if you think those issues are "blah, blah

Not all users.  And you're right; they don't care what
*your* choice of browser is; they'll just leave if you tell
them to "upgrade" a Volvo to a Gremlin.

Wait a minute; you originally wrote:

>added to the search engines' indexes.

Which is it?  Internal uses, or content-rich for search

Well, you came to a forum where most people do care.
What did you expect the reaction to be?  But more
importantly, we know that it isn't necessary to restrict
your site building to one browser.  You asked the equivalent
of "how do I do something that almost never makes
sense?"  So forgive us if we have a few questions first ...

I understand that it isn't a very nice feeling, to feel
as if your question is being picked apart.  But you can
now bite your tongue, grit your teeth, and learn from
the experience, or you can lash out.  Up to you.
