They still have the activity page down… Which broke tumblrstats, they will probably be making their own system that’s just like the one I made. For the time being I fixed it so it can still track posts, and followers.
Large sites like this should not be killing a feature for weeks to release a updated version. The development process doesn’t work like that.
use it while it lasts: http://tumblrstats.icodeforlove.com/ (that’s until tumblr replaces it with their own copy)
Dude that’s slick. I never knew about it.
