Webcomics are an odd medium. Much like everything that's been converted to the internet, they're much shorter and normally much more freeform than traditional comics. There is no short supply of webcomics. There are even many good webcomics. Most of them are sort of one-offs, with one joke and no continuity. The comics that do have a continuous story arch, aren't normally that good. The quick hit-and-run style of the internet doesn't work well with well-structured, well-written literature.
So it's surprising that Misfile is just so well written.
