It looks like Fluther is trying to make a Q&A site aggregator (See Fluther's website and TechCrunch post on it). It claims to drive more traffic to sites that partner with it. Has SE looked into partnering with them? Are we already?
What is meta?
- Any Stack Exchange user can ask a question
- The community provides support, votes on ideas, and reports bugs
- Your voice helps shape the way Stack Exchange operates
Fluther's Federated offering doesn't seem focused on being a cross QA aggregator--it's a way to embed their QA engine into externally hosted (and putatively public) sites. The aggregation is of embedded Fluther Federated QA content back into Fluther.com.
Simple analogy: if you could embed a small version of SE into your own site and then have that content rolled up into SE.
Federated isn't aggregating Yahoo! Answers, SE, Quora, etc. That exercise is left to some startup already out there working on that and getting it's YC application ready... ;)
No. I often see SO results in Google, indicating the popularity and technical expertise of SO. But I've never once seen Fluther in those results.
