In July, Google’s arrangement with Twitter to index all tweets, make them searchable in realtime and have a REAL historical search database of tweets that goes back further than the recent past (a trick that Twitter itself can’t seem to figure out) came to an end. It was a blow to both parties because Google lost a valuable piece of the social graph for its index which limits its abilities to take real social cues for search results and Twitter lost 65% of the US search market and even larger chunks of that market internationally.
Now some would say that Twitter should be fine because it still has an arrangement with Bing and Yahoo to do the same with its search results. That sounds nice but it’s the same as saying rather than drinking Coca-Cola you are only allowed to drink the grocery store version of a cola instead. Sure, you can say its cola but it ain’t the real thing.
