good point in essence but the 'access your house' analogy is a little lame....
denying/allowing access to my house is my perogative... legally I am entitled to
apply a racist/prejudiced door policy on my own frontdoor - however abhorent
such an idea might be to the most of us.

and the same goes for a site I create - I'm entitled to grant/deny access to whomever I please,
in the real world this most often translates into constraints that are placed on
intranet/extranet systems whereby your userbase is known/controlled and
certain functionality may require a decent browser (as opposed to the POS that is IE ;-)

.... and sometimes its is completely valid and correct to deny access.

----

having said that if you want to attract customers/users to your content then
forcing them to use specific applications/tools to do something which could be
handled by any number of different tools (on different OSes) is plain stupid...

oh and if anyone here works at a bank, maybe not forcing users to use IE when visiting
your site would make you look less like monopolistic idiots (why is it that the
organisations with the most freaking money are the least capable of providing a
_proper_ site...?)

Welcome to Monday ;-)
