Useful RSS
One of the most practical and ingenious uses of RSS I have seen in a long time can be found at EbayListings.Net FreeBiddingTools.com. Here you can create custom RSS feeds that will monitor ebay searches of your construction. Looking for a certain item? Setup an RSS feed that will hourly (or as determined by your aggregator) show you all ebay auctions that match your query. Filterable by price, seller id, gallery, etc. Seems like you could also use it to monitor your own auctions as a seller. Very nice!
Its not clear from the site, but I suspect this is an ebay venture. Here’s hoping it will be integrated into the main site. It would be nice to have a “subscribe to this search” feature within ebay, itself.
Update: I just got an email from Brad who runs EbayListings.Net FreeBiddingTools.com, contrary to my assumption that it was an official ebay offshoot. Due to legal issues the site’s URL has changed to www.freebiddingtools.com. I’ve modified the link above to match.
