Several differences between the Yedda approach and the Wondir approach though -
1. Yedda lets you define just how much and how often you would like to participate (3 questions a week, or 5 a day, etc). So you won’t be flooded with the hundreds on question on Techcrunch

2. The Yedda semantic engine understands the semantic behind the “keyword” , so that if you subscribe to Techcrunch, Yedda understands that you’re likely to receive questions related to “Michael Arrington”, CrunchNotes, CrunchGear, “Web 2.0″, etc. Of course, the more relevant the question is to “TechCrunch”, the more likely you are to get it.

3. While you can subscribe to all questions on a topic, and you can answer any question you’d like, the default Yedda approach is to send a question to the “right” amount of people, so as not to flood everyone with a single question. It’s all about optimizing attention. There is only so much attention out there, and in a way, it’s a “waste” to have all this attention directed to a single question, leaving other questions unanswered.

I apologize for the somewhat lengthy comment, I hope the differences are clearer now though. Of course, each approach has its pros and cons.

Perhaps if FunAdvice got some funding, they’d be bigger news, but so far, Yedda & Yahoo Answers seem like “me too’s” of a far older product, imho.

HelpShare also has the ability to set up Expert Alerts which can be delivered via email, RSS or IM.

The best thing about HelpShare is that the focus is on powering EXISTING communities. So other web sites can get the power of Q&A without having to build it themselves. For an example check out Chris Pirillo’s site at http://helpshar...lockergnome.com.

And if you are a blogger, you can also generate revenue by becoming a HelpShare affiliate (http://www.help...s_affiliate.asp) and you get a piece of all the transaction revenue from questions you generate or come from users of your site.

The debate between points and $ will continue and definately has a direct relationship on the quality/quantity tradeoff. While the sites at http://www.helpshare.com and Lockergnome are implemented in $, the HelpShare Q&A platform can be delivered in a points model as well.

So for sites who like Q&A or bloggers that want to engage as well, HelpShare has an answer.

didn’t work in firefox on OSX

tried clicking the feedback but site wouldn’t respond

posting this here in hopes they read techcrunch

We had a major users visits peak right now, which exposed an issue with our home page – that cool scrolling list of recent questions was, well, not implemented optimally… we disabled it for now (actually slowed down the scrolling considerably), so things should be back to normal in a few minutes.

I apologize for the performance hiccups you’ve been getting!
