i tend to draft everything lowercase, and then go back and uppercase things depending on how much of a formal vibe i'm going for. capitalization rarely helps me formulate an idea, and so my writing often splits into phases: (1) formulation, (2) polish.

also, it's worth noting that proper capitalization does not automatically yield text worth reading. from that perspective, i like lower case text as a form of rebellion against the artifice of rules; any rebellion against particular aesthetics is fair game in my book. more generally, i'm skeptical of process advocacy in cases where the process seems to be done for its own sake.

on the flip side, good grammar helps me parse sentences, so i do sympathize with arguments in its favor.
