Best Q&A Website Software for SEO?

[TheDude]

I am looking for good (paid or open source) Q&A software for my website.

My industry is very confusing to most of our clients and is boring in general.  Therefore, we don't think we'll have an active community (so we don't want a full fledged forum), but more so just 1-off questions from potential clients for each product.

I'm trying to find a solution that...

• Can be indexed by Google (I want the longtail traffic!)
• Easy to post a question (simple login w/ possible FB, Google, Twitter sign-up)
• Feeds for most recent, popular, and featured questions

We run a custom HTML/PHP site, so I'd like to add it to product pages to allow people to easily post their questions.

I found some possible solutions like QHub, but nothing that I'm sold on yet.  Anyone have suggestions?

We have a Q & A site and used this wordpress template. Don't believe they have login integration as you mentioned, but has the rest of the functionality you mentioned. PM if you want to take a look.
