Speaking only for myself, I want a few different things out of a service like this.<p>For one, I want an article fingerprinting technology. One that can tell that multiple different sites are talking about the same original post, and not really saying anything that is materially different. Maybe they all just cut-n-paste (which something like Churnalism would hopefully address), but I also want to catch the sites that add a little unique content to an article, but not enough to make a real difference. Link analysis would have to be factored into this, based on the full expanded URLs -- Sometimes there are new articles that come out with additional information on a topic that has previously been discussed, and I wouldn't want to miss those.<p>Second, once you have the fingerprint for each article from each site, you need a fuzzy way to compare them for uniqueness -- I want to do a "sort -u" on all news articles, based on the fingerprint.<p>Third, I need a way to tweak the scores and settings, so that articles from a high quality site like Ars Technica gets rated better than a lower-quality site. Of course, a certain amount of automation can be used here to generate default scores and settings, but I may have a different idea of exactly what scores and settings I want to use as compared to someone else.<p>I do like the idea of taking input from sites like HN as an additional variable for the positive or negative weighting of a news story (or a particular news site), if the article in question is one that has recently been discussed there.<p>Of course, you also need the concept of pluggable modules, so that when the next new thing comes out (like Churnalism), it can be quickly and easily added to the mix.<p>I don't suppose this sounds remotely familiar to anyone? I've got a bunch of feeds that I watch, but there's a lot of duplication and I would dearly love to be able to filter out that chaff while still allowing through the occasional unique article from those sites that usually just jump on the bandwagon long after the horses have escaped the barn.<p>Thanks!
