Make Your Twitter Sidebar Transparent
Here I found this somewhere on the web. A simple trick to make your Twitter Sidebar disappear just like “Sim Salabim Jadi Apa? Prok! Prok! Prok!” :)

Ok, first thing first you need to Login to your twitter account. Isn’t it so obvious? unless you can login to other’s twitter account but i should never suggest you to do such a crime.
Now go to your “Profile Design” Settings, it should be around here: http://twitter.com/settings/design (you can just click the link to get there faster)
Now Copy the code below:
javascript:document.getElementById("user_profile_sidebar_fill_color").value = '';document.getElementById("title_theme").innerHTML = 'Click The Save Changes Button At Bottom To Finish!!';void(0);
and Paste it on your Addres Bar (what is Address Bar?) at the top of your browser, and hit Enter.


Now you won’t see any changes until you click “Save Changes” down in the bottom of your screen.

That’s it! Go see your profile, there won’t be any sidebar in there :D
please note that at some moment in the future, Twitter will prevent this from working.
