Because it sucks.
I haven't used it in years and just this week noticed that some of my posts look awful in IE. Look:
|Internet Explorer: the videos crush.|
See what I mean? Another example:
|Even when the picture is X-Large Opera shows it ok.|
|Same in Firefox.|
|But oh no, Gary looks really blurry in Internet Explorer, even when I changed its settings.|
I used to think that Internet Explorer was a good browser. But then I found Firefox.
I used to think that Firefox was the greatest browser ever. But then I found Opera.
I used to think that the Winamp was the best audio player in the history of audio players. And I haven't change my mind.
Well, I lost my point. The thing is that Internet Explorer sucks.You should change it. The other browsers look and work much better.
