All About Symbian conveniently covers the many promos run by different companies to push for more contributions to their corporate wikis:

Sony Ericsson Developer World wiki and Symbian Developer Network wiki are both holding competitions, with Sony Ericsson giving out one brand new top-of-the-range Sony Ericsson P1i to one lucky contributor. Nokia also hold regular competitions including a 'contributor of the month' award who wins their choice of S60 3rd Edition device. Symbian is giving out one 'in-a-class-of-its-own' Nokia E90 communicator, one Nokia N95 'multimedia factory', two 'UIQ-tastic' Sony Ericsson P1is, and a 'never get lost' Nokia 6110 Navigator.

Is the prospect of winning a Symbian smartphone enough to make you basically hand over your content to the corporations?
