...standards were adopted...
The good thing about standards is that there are so many to choose from.
I stopped designing web pages when Netsape 7 was released as some of my scripts fell over. Fortunately the changes did not affect any of my commercial scipts.
If someone comments that something does not work in FF I often point them to http://www.thecounter.com/stats/2007/January/browser.php and suggest they wait until that browser has enough users for me to warrant the effort.
FF was catching up with IE until IE7 was released. I do not really like this browser and can only imagine that new computers are being shipped with it preinstalled.
A slightly off the mark example of what's on my mind is a menu system I developed for a small hospital. The techs complained it was not NS4 compatible. After I requested the browser usage stats log they were shargrin to discover they were the sole users.
(Don't mind my ramblings, sometimes it's just good to leave a message for people who understand what I am writing :-)
