a couple of 10 dollar words for a simple idea . . . .
what if an aggregator monitored how often:
* you clicked through to a full post from a truncated one in a feed
* you read all the way to the end of a full post if the feed provides that
That way, you get a sense of how useful you find the feeds you’re subscribed to: an extension of that would be let the aggregator sort your feeds by how often they get a close reading.
