Going through, stumbled upon this nice source code:

<!--[if lt IE 7]>
<p class="chromeframe">You are using an <strong>outdated</strong> browser. Please <a href="http://browsehappy.com/">upgrade your browser</a> or <a href="http://www.google.com/chromeframe/?redirect=true">activate Google Chrome Frame</a> to improve your experience.</p>
<![endif]-->

Just out of curiosity, what would people heavily using IE do, if they’re offered Chrome. Ignore, or upgrade their IE?
