Want a low-cost, fun and effective way to reward your most active Facebook contributors? Steal a page from Cisco, whose corporate page is one of the best B2B presences on Facebook.

Last year, Cisco started the SuperFan program to recognize its best community members. Each month, administrators recognize one fan and highlight him or her at the top of the page. Two of the monthly winners were just chose as SuperFans of the Year and celebrated on the Facebook page as well as on the Cisco Platform Blog.

Winners get no cash or large prizes, just some Cisco swag and lots of thanks and exposure. Co-winner Sandee Weiner commented, “VERY VERY proud of reaching SuperFan status with Cisco! I’m pretty passionate about technology and the way social collaboration brings folks together.”

Cost to Cisco: next to nothing. Value: a lot more than that. Next up is a photo contest challenging people to show the Cisco logo or products in the most unusual or exotic places. That’s another great low-cost idea.

So was last year’s Crazy Cabling Contest.
