July 16: Tina Palmer shared a post called "What I Learned at Twitter Math Camp Today (and it had nothing to do with math)." As the title says, it's not about math, but it is a passionate reflection about relative safety and the communities we can create for each other.

July 18: There was a tie between six different posts shared five times each, but the only math-focused on with new content was "10,000 Kicks: Practice in the Mathematics Classroom," an NCTM Mathematics Teacher blog post written by Tim Hickey, a high school math teacher from Virginia. The post struck a nerve with some, as the math community is hardly unified when it comes to the issue of worksheets and practice. NCTM's choice to publish and promote this is an example of the growing pains I think we'll see as they try to give more voice to their members and those members do not all agree.
