Whenever any post is updated, the feed for that is sent out again, and the whole post appears in the aggregator. Now searching for the updated part is very difficult, unless the writer has explicitly used Update.
I want a feature in Bloglines/Google Reader that would highlight the updated part, or present the updated part in such a manner such that it is easily noticeable. And yes, there should be an additional utility, which allows me to ignore those updates that just changed the errata; I should be able to specify that this is the number of words that must have changed before fetching the feed again.
I know it’s a bad demand, but I am too lazy to search for updates and I also cannot ignore the item, as there may be a good, interesting, newsworthy update.
Does any RSS aggregator provide any such feature?
