There were multiple accounts with hundreds of thousands of followers. One with 1M.

No it's most likely just overconfidence in the market by a few individuals.

Intrade actually checked for manipulation themselves:

"We checked this out for potential manipulation - it certainly fit the pattern at first glance. However, during the period you reference above 40 individuals bought Romney shares and no individual bought more than 15% of the shares traded during that period. A look at those 40 accounts shows nothing suspicious. So we don't believe this was manipulation but more a run on Romney when the market was unusually thin."

However, even without this spike the Intrade market was misaligned for more than 24 hours. A few of our arbitrage customers made huge amounts of money (outside our software) trading 5-10% arbs between Intrade and Matchbook. This is extremely uncommon.

Thanks, I've been waiting for this. It's still experimental (under "about:flags"). Stacked tabs are great, but unfortunately "tab grouping" is not that, it's just a feature that makes it possible to select several tabs at once?!

With real tab grouping in Chrome, including a feature to only load tabs when selected, I could finally make the switch from Firefox and the great "TabGroupsManager" addon.

Unfortunately, Chrome dev team decided that opening all tabs on startup is a good thing and marked intelligent lazy loading of tabs as "won't fix". I cannot find one good argument against this feature, unless it's extremely difficult technically (which is unlikely).
