I don't know what Google+ is doing under the hood (and don't really want to know) but whatever it is seems kind of bloated to me, enough to kill my browser and the responsiveness on my whole machine when I try to open 14 G+ tabs at once. But anyway, here they are:
Sexism and bureaucracy at Wikipedia and an update on the Walter Lewin sexual harassment story (G+)
Wisconsin gov. Walker seeks major cuts on universities so he can build a sportsball facility; Calif. gov. Brown isn't much better (G+)
Super eggs: the mathematics behind the shape of, among other things, Azteca Stadium in Mexico City (G+)
Cal State Univ. gives up on Wiley journals after hefty price increases and refusal to unbundle (G+)
Topological Tverberg counterexample. It is true for all prime-power dimensions but that wasn't good enough to be true for all dimensions.
Randomly cut and flipped rectangles from another Tumblr of interesting mathematical visualizations (G+)
1961 interview with F1 racing driver Bruce McLaren's family. From my mother's blog; McLaren was her second cousin.
