While they didn't succeed back then, but maybe it was just an idea ahead of its time. Look at the recent developments in internet advertising. Google has become an advertising mogul (they even own this blog), and advertising money is flowing, no gushing, into the internet because advertisers have realized the potential power. To ride this new wave, one company has come back with the Viewbar: Agloco
Agloco is in its initial stages, so if you jump on the wagon before everyone else, you have the potential of earning bookoodle bucks! They don't have a working Viewbar yet (it's in beta), but you can still refer friends, and as soon as the Viewbar is up, you'll see coins flowing into your coffers. The more people you tell, the more moolah in your moneyclip. Ok, ok, the alliteration is getting a little out of hand.
I'm still a bit skeptical because my dreams were crushed from the last time around, but it costs nothing, and it carries no risk, so I say, why not?
