I empathize with the idea that readers of Planet Emacsen probably shouldn't be forced to read my poetry, much less the very-rough-draft poetry that's happening around here during the month of April. (Though in its defense, it is written in Emacs, using Muse even.)
Unfortunately LiveJournal doesn't seem to provide feeds by tag. But I made a Yahoo Pipe that will deliver just the Emacs posts. So if people would prefer to have only the posts tagged with "emacs" appear on the Planet, then this feed is open for business.
