I got a random email the other day from some guy telling me about this new site he just put up: http://knewthis.com. Apparently he found me through Ezine Articles. It's supposed to be like Yahoo answers where people ask questions and get answers on them. He said all of the links are do-follow as well. Also he said it's allowed that you could ask questions and answer them yourself to start bringing targeted traffic to your site. Have any of you heard of this or used it yet? If so, any good results?
