Big Wide World

too many people i know are still using IE and i can't figure out why.

am i missing something. is there something actually good about IE that i just am not using? i don't think so. but lets do a comparison of what i have in firefox to IE:

* firefox: awesome extensions like tabs, customized tabs, adds ins for del.icio.us/clipmarks/kaboodle/evernote/mystickies
* create your own searchengine (rollyo)
* great skins
* highlight text

well, i don't want to go on and on, those are just a few of the things that i use daily. but with all of these things, and less security and bug worries, why would someone still use IE?
