Meebo is very proud of this bar, for reasons I don't entirely understand. I can see a fair amount of use for it, on some websites, but I really wish they would optimize it so that those that opt to implement it on their pages don't get such a performance hit to pageload.
The bar from www.wibiya.com is even worse. Not only is it slow to load but it has notification pop ups and a bunch of other crap.
I'm sick and tired of all the sites that have decided to add bars to the top and bottom of their pages and a billion social network buttons all over the page. I'm at the point where even though I'm blocking most of them via adblock new ones keep showing up so I just give up and stop going back to sites that use them.
