Hopefully You Keep More than One Bar of RSS Feeds
I've found that wikispaces provides RSS feeds for individual tags, so you can subscribe only to what interests you. In that respect, at least, it's a good thing that I'm posting much more stuff there than here. It's much more organized than spouting off stuff that I have to muck around to find. It's also indexed on Google, so it'll hopefully be slightly more likely to generate response (since people will go back to pages rather than ignoring each post just once).
