Brew your own newswire
Rael Dornfest from O'Reilly has announced Meerkat 1.4, the latest version of his headline service, which allows you to synthesize custom newsfeeds for your sites.
Meerkat aggregates headlines from sites around the web, using the RSS format for expressing headlines. You can then read pre-selected "flavors" of news (e.g. Linux, Wireless) or create your own permanent searches over the day's news.
