Fredi Bach made a really cool RSS feed aggregator.
“Well, basically this is a feed aggregator. That means it takes the headlines from other sites, mostly blogs and archives them into a database to make them easily searchable even if the original feed was updated. Additionally to those â€œnormalâ€ features it shares with other good feed aggregators, jMe let’s you select feed items and arrange them in a collection. This collection can than be posted to other websites, weblogs or message boards.”
The tool includes some pretty advanced search techniques, and the collected feeds include posts on OS X, Web 2.0 & programming.
What an interesting way to collect and then find information!
