(I apologize if this is the wrong forum for this, but it seemed more appropriate than the main math site...)
So I got sick of keeping all my notes spread across Mathematica and vi, and wrote a tiny website platform to let me do my math musings and easily share things. Basically, I wanted something that let me quickly and easily jot down stuff with markdown and latex.
I've been using it for months and it's great for me, but I have no idea whether anyone else would be interested in this sort of thing. So if you want, see it / try it / use it at http://stacked.by.tc.
If there is interest, maybe I'll try to polish it up some and release it into the wild. If there's not, that's fine too, less work for me. :)
