I am in the process of writing a RSS reader. I want the user to be able to search for RSS feeds on the web by keywords and subscribe to them. Currently I am using Google Feed API which allow me to send text queries and receive all relevant RSS feeds from the web. Then I can take the feed URL and parse it for user reading / subscribing by saving it / share / and more..
Are there any other services like the one Google is offering? I am looking to aggregate some more RSS feeds search providers so the application wont count only on Google.
