Tonight, I will be at Beers and Innovation 8, which is discussing attention. It's only £15 to attend - which means I have so far managed to get in to March without breaking my new years resolution of spending more than £20 for a ticket to a tech event. 
I've just installed the Attention Trust tracker in Firefox, which is churning out (not particularly well-formed) XML of everything I browse (there is a button to toggle if I don't want it to record my clickstream).
It would be trivially easy to write an attention tracker which would turn this XML file in to RSS, OPML, RDF etc. I'm excited by the new features in XSLT 2.0 that allow grouping (xsl:for-each-group).
An application I'm thinking of building would be called my "attention bundler". What it would do is take everything I've been browsing, pull other data that I've been producing (last.fm, del.icio.us, Flickr, my blog etc.), mix it all up, produce some interesting results and upload them. It'd be a desktop application - perhaps just a button on my Dock which I could hit from time to time and all sorts of magic would happen.
Is this too geeky? Of course. But that's one way in which we can research how others can use it. We piece together geeky stuff, then test it out, and if we like it, make user-friendly versions of it.
