Oh Whip me baby! Feed me; Feedwhip RSS for any web page
Simon Willison linked to Feedwhip. I love this idea. It’s very much like a Mac OSX App I’d been using, Changes Meter. The basic idea is that it provides an RSS feed to changes that happen on a web page that doesn’t have a feed. I use my feed reader a lot for all sorts of things. Changes Meter was an OK stop gap, but it’s nice to be able to monitor things with my feed reader again.
There are a couple of caveats, though. I wonder how well it works with pages that have dynamic elements like Ad beacons which are randomly changed. That could easily pollute a feed to the point of uselessness. Feedwhip is also pretty limited with the amount of feeds and the refreshes frequency. A standard user gets 5 feeds which are refreshed every 48 hours. Right now they are giving a free 180 day upgrade to the Pro version which gives 10 feeds refreshed daily. Still not too awesome.
Netnewswire has an option to subscribe to so called special feeds
. These can be a few of things, but particularly a script or a flat file. While you could make cron job to do diff curls against each other and publish the results, I like the idea of a live script better. Being able to cook up scripts which muck about with feeds is another reason why I like local feed readers over web based ones.
Technical limitations aside, what I liked best about Feedwhip was the idea of getting a feed for information from anywhere. I’d like to see something which takes this further and produces a usable interface to page scrape directly into a feed. Something like that which could be thrown at Pipes would be incredible. A user could create a feed of any information they wanted without any coding at all and subscribe to it with any feed reader at all.
