Is your shift key busted or what's the problem?
it started when i originally joined the forum as a dumb attempt to obscure my writing style, and now it's just inertia. it seems too late to stop now!
i suspect sophisticated textual analysis would be able to discern my identity anyway, although the technology is probably not good enough yet for an undirected attempt at doing that to succeed.
i have a tendency to write like an adult, which is to say in paragraphs that mature people might read. that does not seem to be the style of this forum. perhaps not capitalising my text serves as a useful reminder for me to stop writing too much.
