User Powered Live Support
Nothing is more effective than a live instant message style conversation with someone knowledgeable. Members post their questions or requests for help and remain logged in to the site until another Teksup user accepts the request, starting a live chat session. Chat logs are then saved and indexed for search. Members can also answer questions offline, much like traditional Q&A sites. Use of the site is free and open to all.
Teksup also provides real incentive to participate. Members can choose to tip those that help or solve their questions with payments via PayPal. Preset amounts between $1.50 – $20 are available to tip. Enthusiastic and knowledgeable users of the site have the potential to make substantial income by being available and active.

Pretty cool. I’d say it’s a mix of yahoo answers + get satisfaction + live chat.
