In Information Aversion, Dave Shea notes that he finds combined RSS feeds annoying. Reading the comments, it's obvious that others do too. Personally I don't mind combined feeds as long as they aren't littered with personal stuff, which is rarely interesting unless you know the person IRL.
Anyway, since it's so easy to setup, this site now has a feed that contains only my main posts. No Quicklinks. If you want to separate things, you may want to unsubscribe from the All posts feed, and instead subscribe to the Main posts and Quicklinks feeds. Or just one of them. Or neither.
