ComScore's latest search market share numbers are out, and the search giant Google is slightly less dominant than it was at this time last year. While still holding on to a healthy 65% of the US search market, that's less than the 68.7% held by Google at this time last year.

It was announced back in February that a new deal was struck between Twitter and Google which would see the indexing of tweets in Google's search results. Now, six months later, the promised new feature is finally live.
