I remember when I first came across Slashdot.org. It was years ago - it must have been, I was still an employee as opposed to my current freelance status - but one of the main focuses of the Slashdot website was free software. At the time Linux was relatively new in the conciousness of the IT professional, even those of us who had been using free software for years at the time.

They key to slashdot was that it aggregated news items from a huge variety of sources and topics into a single feed that would appeal to the Geeks among us. It covers a lot of material - everything from space exploration and science through to BSD, Linux and Perl.
