To further this argument, I'd even go so far as to reiterate what has been stated earlier on this thread that not supporting old browsers is absolutely unsustainable. If you don't upgrade your computer you're saving mountains of global resources required to create a brand new shiny computer. Endlessly creating more and more advanced electronics to endlessly buy is simply masturbatory consumerism. I'm not against enjoyment, I certainly enjoy video games and the lastest episode of Glee, but that one MUST have the latest iPhone 4s, the hugest screen kadoodle pixel width TV, etc. and that you MUST UPGRADE NOW!!!!!! If you want to force your blue ball obsessions down everyone elses throats --- well you better just give up now, cause you can't do it, cause WordPress is so great and flexible and thus ---- there's a plugin for that. :)
And so now people everywhere are clicking off the nag, they are turning the nag off with a plugin.
