When I stay up way too late, I play with ciphers!

The plaintext should be familiar. The way I'm hiding the information is something I came up with as a start of a more complicated system of enciphering. Dunno how the end product will look, and I'd like to try and move away from straight English letters (verbose cipher, anyone?) just because I like that particular challenge.

If you want to guess at the solution, PM me. Solving the puzzle also means you have to understand how I disguised the plaintext.
