BLOGGER: "Now there's One BlogThis! to support nearly every browser regardless of OS. This includes IE 5 or greater on both the PC and Mac, Mozilla 1.0+, Safari, Camino, Firebird, Opera ... pretty much everything greater than Netscape 4. This modern wonder is available here:
BlogThis!

p.s. To use BlogThis! drag the link above to your browser's links bar for quick and easy blogging. Check it out."

A parte boa é poder usar-se noutros browsers e OSs, a Google bar só funcionava no IE.
