One issue I have with Bloglines is that I tend to mark items as new for further reading, commentary, or investigation. I could relatively easily post these to del.icio.us or put them in my clip blog, but I'm so lazy I don't want to even do that. Actually I blame it on the Bloglines clip interface which forces you through a popup dialog, a choice of where to stash the clip, and finally a confirmation window. Too much work!! Unfortunately, I have a big enough pile now of "marked as new" items that they actually make it hard for me to read with Bloglines. There's tons of old cruft intermingled with the new. Cleaning up is a daunting task.
I'd like to write a script that daily pulls down those tagged items, marks them as read, and in a blue sky world, fed them to a personal focused crawler. The crawler would do some clustering, context analysis, and automated search to build a compendium report for me. I'd pick it up the next day in my aggregator or stash it somewhere easily accessible. Call it knowledge aggregation.
This is only slightly more work than Findory, but maybe that little bit more semantic information (I really am interested in that post and here's some other feeds that I think are related to its source) might make a huge difference in finding relevant related stuff. And if search histories were programmatically accessible, hey more grist for the mill. At the very least the combo would help me separate my short term and longer term horizons.
The Bloglines API doesn't look very promising for making this happen. I'll keep digging, but combining post tagging, a web based webfeed aggregator, and a programmatic back end would be a big win.
