Hey guys ... don't know if this has been covered or not ... but Alexa search is now powered by Live.com! I believe, if i'm not mistaken it was being powered previously by the DMOZ/GOOGLE directory ... check it out at http://www.alexa.com/search?amzn_id=alexa65-tb-20&q=furniture&p=TBChrome
It's owned by Amazon, and A9 switched awhile back. I was expecting this, but had not visited the home page in awhile, looks like some kind of blog/commentary - http://www.alexa.com/ - they are calling it "Web Discovery Machine". Interesting. Google loses again. But it looks like DMOZ is still there.
