Review for Ofelio search by Vojsana
Rated 5 out of 5 stars
Useful service to search for relevant rss and atom feeds by keyword. The Ofelio website also permits to search by location for geolocated feeds. Feeds are continuously indexed and re-indexed by the spider, to always show fresh content in queries results.
