 #chartjunk
 
-A while ago, I started working on a sparkline font at the Khan Academy. Instead of writing some obtuse canvas script that would be hard to maintain, why not use a font to represent the same thing? The text then, could be meaningful, and you'd have the advantage that the sparkline display would gracefully degrade.
+A while ago I made a sparkline font at the khan academy when i was working with [david hu](http://david-hu.com/) on creating more forgiving streak bars. Instead of writing some obtuse homebrew canvas script that would be hard to maintain i thought: why not use a font to represent the same thing? The text then, could be meaningful, and you'd have the advantage that the sparkline display would gracefully degrade.
 
-We tried it out and the project went another way, but the font remained. Please edit, hack, update, do whatever.
+We tried it out and the project went another way, but the font remained in its pre-v1 stage. It's not such a terrible idea but it could use some more work (i.e. the comma could be a zero-width character to make rerendered chartjunk legible again). Please edit, hack, update, do whatever (but please, only for good, never evil).
 
-In this project, i'm providing it both as a css base64 encoded font (for webpages), as a UFO file and also as an OTF. I don't have any current intent to support this at the moment, but sparklines are always interesting and having tools available for implementing them is always nice.

+There are probably other tools that do this better, so you're probably better off using those, but if you like this, then hooray!
