There were three issues of Kaleidotrope in 2010, #8 (April) and #9 (July), and #10 (October). That's more than ever for the 'zine. Between the three there were 33 new stories, 4 novelettes and 29 shorts (8 short-shorts -- the 'zine has always featured a lot of short-shorts, though this count is actually down somwhat from the past), a bit more then 120,000 words total. There were also quite a few poems, and some nonfiction. The editor is Fred Coppersmith.
From #8 (April) I liked Fred Warren's "The Silver Tree", YA flavored SF about a colony planet and an unsanctioned plant; and Rob Hunter's very odd "The Beewolf". From #9 (July), I liked Jay Lowrey's "Som Many Years Ago", about a crowded future with mandatory sports rooting fees, etc; and Cort Ellyn's "Fire Eater", about a woman's attempt to reform a prison for magical creatures. From #10 (October), Ian Faulkner's space adventure "Krishna Blue", about AIs and an oppressed planet and revolution. Other good work came from Bonnie McDaniel, Genevieve Valentine, Rachel Swirsky, Maria Deira, Terri Leigh Relf, C. Groover, Benjamin Smith.
By my count, 13 of the 33 stories were SF (39%), and also women wrote 14 of the stories (42%).
