Yahoo continues to add RSS feeds, and these are cool ones for kids:

Ask Earl (http://yahooligans.yahoo.com/content/ask_earl/earl_rss) (a daily question and answer for kids)
Word of the Day (http://education.yahoo.com/rss/wotd/)
SAT Tip of the Day (http://education.yahoo.com/rss/sattip/)

According to Jeff Boulter, the engineering manager for Yahoo News, more are on the way -- stay tuned.

A good list of RSS feeds offered by Yahoo is here: http://news.yahoo.com/rss/ (note the additional links for business, entertainment and technology categories).
