It helps if you can donate some of your time to an open source project that's complementary or related to what your company does. For example, I volunteered to write the tutorial for Sigil (http://code.google.com/p/sigil/wiki/BasicTutorial http://code.google.com/p/sigil/wiki/BasicTutorial) because it's a great alternative to the closed, expensive InDesign product (http://www.adobe.com/products/indesign/ http://www.adobe.com/products/indesign/). Tutorials or presentations are also good. I created a basic overview of how to create an e-book, and presented it at BarCamp5 in NYC. After the conference, I posted the slides and links on my personal site (http://denis.papathanasiou.org/?p=286 http://denis.papathanasiou.org/?p=286). As a result of both activities, my company's site (http://www.fifobooks.com http://www.fifobooks.com) gets traffic and business (new registered authors and readers, as well as other opportunities I hadn't expected).
