The Personal Bee is a Berkeley start-up that lets users organize news in their area of interest, so that others can read it.
It is chock-full of the latest Web 2.0 features, and it worth taking a look at.
Rather than forcing you to rely on what the wider community of readers decide is important news, which is what Digg and Memeorandum do, Personal Bee lets “beekeepers” do the deciding, and gives you the beekeeper the infrastructure to organize and filter news however frequently you want. Anyone can become a beekeeper (though it is still in testing mode, so you have to request). Meanwhile, other readers can sit back and enjoy the beekeeper’s filter.
