In one of the photos, Mayer is seen standing beside a well-stocked bar in the offices of Flickr. Flickr team members stand listening to her. Boxes of donuts are on the table.
This is kind of a big deal just because Yahoo is widely seen as having screwed up social photo sharing. (See: Cramer: How New Yahoo CEO Could Become Its Savior)
At one time, Flickr was hugely popular. I remember I used to log in to my Flickr account every couple of days to see what my friends were sharing. My friends did the same thing.
Hardly anyone I know does that any more.
