I don't know of an ultimate feed list, other than finding someone with a similar need and hoping they already have a subscription list you can steal.
This is why I'd like to see a concerted effort - in the library community at the very least - to provide either an aggregator with pre-populated feeds or opml files of feeds by type of library or interest. Get the K-8 teachers to list their favorite sites and provide the feeds in an opml file that a new user can import in order to get started. Same thing for 9-12, reference librarians, academic librarians (even better, by specialty!), medical librarians, law librarians, technology librarians, etc.
Hmmm... maybe I'll have to set up a wiki for this, too, and then I could point users at it when I give presentations about RSS.
Wednesday night is the big blogger dinner here in Chicago. I plan to spend most of the dinner at Ben Pao (7:15 pm, be there or be square) basking in the conversation of:
Rick's got every detail and the reservation, so please let him know if you are coming.
Blogroll (Sites I Read in My Aggregator)
Mobile Blogroll (Sites I Read on My Treo 600)
Spreading the meme:
Why You Should Fall to Your Knees and Worship a Librarian
