Dapper, Pipes and Plagger a meta-mashup, an article that sums up three new Web 2.0 products for interacting with feeds.
Dapper allows you to create your own feeds for websites that don’t have them, or ones that do that you don’t like their feed (maybe it has ads or partial summaries of articles). It has an awesome interface where you literally click on the parts of the website you want to use.
Yahoo! Pipes allows you to take an existing feed, or one out of dapper and mangle or change the data. Its great at selecting the parts you want and reformating it into RSS, XML or something else.
Plagger… well I’m not totally sure what it does.
