Browser Trick for LJ

If you save this as a bookmark on your Toolbar for Firefox or MSIE, it'll pop up a window and ask you for the name of an LJ User. It'll then open up their LJ (you'll have to be logged in before you use it to see there locked posts).

JavaScript:void(q=prompt('LJ User: ',''));if(q)void(location='http://'+escape(q)+'.livejournal.com/')

Here's a similar one for Google Maps
JavaScript:void(q=prompt('Location:',''));if(q)void(location='http://maps.google.com/maps?oi=map&q='+escape(q))
