RSS Feeds seem like a vital tool to those of us who are ”merely” operating a weblog or personal web site. If the primary reason my site exists is to comment on other sites, the news and occasionally interject an original thought, it would seem my RSS feed subscriptions are pretty important.
Beyond the list of 100 most popular that exists somewhere in Radio Userland, where does one go to find RSS feeds? If I go to (e.g.) Fast Company magazine, do they offer RSS news feeds? How does one know?
On another subject, if you enter a title on a post and think better about it later, can you delete only the title, or must you delete the entire post?

A. Looks like you have to delete the post and re-enter it without the title.
