I found a few new* blogs recently that look very promising... (in no particular order!)
1. I Hope This Old Train Breaks Down from Mimi in El Salvador
2. Long Tails of \int_e^r est from CalcDave in Tennessee
3. Without Geometry, Life is Pointless from Avery in California (love the name of the blog!)
4. The Space Between the Numbers from someone (couldn't find a name anywhere... anyone know?)
*By no means are these necessarily new blogs. Just new to me.
