Scott Leslie recently wrote about using Rollup to put together a super feed of his favorite educablogger’s furl and deli.icio,us feeds:
lots of folks have separate Furl and del.icio.us sites/feeds. I’ve been subscribing to one or two of them in the past, but wanted to get all the ed tech bloggers’ bookmark feeds in one place. So off I went to Rollup.org, where I created a new RSS feed that rolled up the Furl or del.icio.us RSS feeds from Alan, Brian Lamb, James Farmer, Greg Ritter, George Siemens, Trey Martindale, Harold Jarche, Will Richardson, D’Arcy Norman and myself. I would have added more, but these were all I could find.
So the handy thing about this is that I can subscribe to one feed in my bloglines account and see all the URLs collected by all these brainy folks.
which is syndicating from http://rollup.org/rollup/rollup.php?id=495
So we can say Scott is doing some new ripping and mixing of feeds, stuff we like to see. I’m not very familiar with what RollUp does– it sounds like what Blogdigger spins out as well- the nifty thing Blogdigger does that no other web-based RSS tool does is to save a cache or history of past entries that have come through– do old items in Rollup fall off the edge of the Roll? I think Bloglines keeps a record as well (true?)The downside of Blogdigger is the lag sometimes 24 hours, for new content to appear.
The other thing I noticed peeking at the source is that Rollup seems to mal-parse the Furl pubDate fields (you can guess that is happening if dates appear as December 1969) and seems to mis the Furl descriptions tags… but wait a mjinute, I peeked at the source of my own Furl RSS and see that Furl lumps many things it;s own RSS 1.0 custom fields (which is perfectly XML valid) but note that odd </description> tags that have no opener:

<furl:clipping>Think of Podcasting as something like a
Tivo for your iPod (though it isn't exactly like that).
which looks a little less than kosher to me.
I am trying to make a point that mixing and recasting RSS can be a tricky thing, and have to admit that Feedburner does a rather elegant job of translating different RSS formats to a clean format. Actually my use of Feedburner was purely an experiment to what they did- I cannot say it really has a grand penultimate purpose.
That said, my using Furl has really not been in the interest of publishing anything important to others- it is my own source for tracking relevant sites that I can come back to and search later. It is purely selfish, It does seem a bit weird at first that others would be interested in my furling, as it is pretty much without pattern– weeks of intense furling to ones of no action at all.
And then I even use del.icio.us to a lesser extent, more out of a curiosity and some experiments to find links to some more off beat corners of the net. I am more interested in the mixing and matching of collective bookmarking both here, and the amazon-like recommending feature of Furl (“People who furled this site also furled….”).
So although Scott lumps me in the “brainy” category, I pretty much do a lot of tapping into other’s links and tagged sites as well. But there is also a huge amount of serendipity when you find interesting links one or two clicks off of these initial forays.
