"The Internet has undergone a major evolution. The real-time information RSS was so astute at delivering (primarily, blog feeds) is now gained through conversations, and consuming this information has become a social experience."
frontsection.net is a tasteful, politically right-on and truly curatorial take on aggregating web content. Careful, combined with an MF habit, this is going to eat up a lot of hours. Although the site is MetaFilter-inspired, all links are the fruit of one intrepid reader whose work, it must be admitted, sometimes grinds to a halt for up to a week at a time.

Upstart travel sites challenge the big three Catering to skinflints who can't be bothered to check multiple sites for the best fares, travel aggregator sites like Mobissimo, CheapFlights, Qixo, or Sidestep allow you to search Expedia, Orbitz, and Travelocity with a single query, as well as bargain airlines like JetBlue and Southwest, which aren't covered by the big three.
