Internet Explorer is a web browser created and "maintained" by Microsoft. It is infamous for having a ridiculously large amount of security holes -- many of them being pathetically easy to execute and often resulting from sloppy, if not entirely incorrect, code -- as well as extremely poor web standards support. Internet Explorer is effectively delaying, if not actively resisting, the evolution and improvement of the entire Internet.
The only reason to use Internet Explorer is to download Mozilla Firefox, Opera, or Google Chrome.
The only reason you should ever use Internet Explorer.
The sole purpose of IE
The best part about Internet Explorer is that it forced companies, such as Mozilla and Opera, to make their own browsers, which completely and utterly blow Internet Explorer out of the water.
Download Opera/Mozilla plz.
IE is buggy, has many security holes, is slow, supports ActiveX so websites can install their XXX dialers on our systems, and finally, it's not standards compliant, so 80%+ web pages have sloppy HTML which doesn't work with standards compliant browsers, only IE. How convenient.
