Apple's Safari Extensions Gallery went live today, and unveiled a few dozens extensions. Unsurprisingly, a few big players were invited to the party, and eBay, twitter, Amazon and Microsoft even took four out of the six slots as the featured extensions. The other unsurprising fact is Google is missing the fun. I know they have their own browser, and so does Microsoft. Either old friends have turn their backs on each other, or someone is becoming more and more arrogant.
