I have created http://www.rssmediacrawler.com. A website that will crawl rss feeds and display them in categories. Guests and users add rss feeds, can post comments, etc. Auto update crawls every hour for new items, interval can be changed. Mod_rewrite for seo purposes. This site is custom coded and designed by me using PHP and MySql. Please let me know your thoughts what is good and bad, what should be added, etc. Thanks.
