There are a few options because not everyone wants every kind of update. Please choose the one(s) you want to add. If you want me to start creating an RSS feed for information you'd want while excluding other info, just suggest it to me here and I'll see what I can do.
Available Feeds:
All feeds: You'll want THIS one if you want to be updated anytime I update ANYTHING, including subdomains (webcomics, Craft page, recipes).
swankivy.com feed: You'll want THIS one if you'd rather only get new content for swankivy.com itself. (The webcomic updates for Negative One are weekly, so if that doesn't interest you, you might prefer this one.)
Writing feed: And THIS is for updates only on if I put something new in the writing section.
Negative One feed: Subscribing to this one gets you just the webcomic-related updates.
So You Write feed: Subscribing to this one gets you just the writing cartoon comic-related updates.
