I use Yahoo! RSS news feeds for my sites (recently switched from Google News since I considered they were allowing too many low quality news providers, like simple bloggers, where I wouldn't want to send my traffic to) and I noticed that some of the news links go to pages where registration, or worse, paying subscription, is required to read the article. Well, that's a waste of link.
Do you any of you know a way to identify these specific yahoo links so I can discard them? At least Google News would add (subscription) in the title which made it easy not to display them with a little regex. I use MagPie RSS but I kow my way around PHP. Thanks for any feedback.
