Today (technically yesterday) I discovered Feed Rinse, a free Web service that allows you to filter and then republish any RSS feed.
I stumbled across the service while searching for a solution to an annoying problem. I’m a member of a forum that posts several torrent files daily. I care primarily about the torrents in one sub-forum, but the forum only publishes a single RSS feed for the entire site that contains dozens of torrents in which I have no interest.
I could use a traditional client-based filtering program or plug-in alongside my preferred BitTorrent client (in my case it would be RSSDler and libtorrent/rTorrent respectively), but I didn’t want to automatically download torrents that made it through the filters. Rather, I wanted to review them manually, only downloading the ones I wanted. However, my on-line feed aggregator, Bloglines, does not support filtering.
Enter Feed Rinse. I can subscribe to the forum’s all-topics RSS feed, filter out the sub-forums I don’t want (provided posters adhere to the forum’s strict titling guidelines), and Feed Rinse will republish the ready-for-human-eyes feed to Bloglines.
