Welcome to WebmasterWorld Guest from 18.104.22.168
It is possible that some editors will add your site but then add a note at the end of your description such as:
[Site may not be viewable with all browsers.]
A majority of editors use Internet Explorer 5.0 or higher or Netscape 4.0 or higher.
But for the sake of the user, browser compatability is a must otherwise you'll lose instant traffic.
Only a small portion of editors will use added phrases o descriptions, some include:
Graphic intense (read: slow loading)
Requires Macromedia Flash (read: no skip intro provided for the nonsense splash screen)
Requires Registration (read: all the good stuff is for members only)
Health [dmoz.org] is as busy as ever.
I figured that since Opera is largely the most standards compliant of the browsers I currently have that it was the fairest place to start
