ya, that looks like it. that was from the original author. i made no changes to the way it retrieves the articles or checks the articles to see if they are old or not. it appears to be checking the title and the date. if both the title and the date of the article are the same then it marks it as old and doesn't enter it.
maybe it could be yahoo updating a news article so the title, link, description are all the same, but since the news was updated the date was different. maybe load up the rss file in your browser and check the pub dates, then check em again later on. see if duplicate titles, descriptions, links have different pub dates.
i know i get a couple repeat articles from yahoo as well.
