It's actually a good source of traffic for me.. Descent traffic.. You can target your visitors as well.
It is still very good but you do get alot of posting links left right and center and there was a software about not so long ago where you could blast out links onto yahoo answers... its great if you dont want answers on weight loss, golfing or how to train a dog lol..... (the most exampled niches)
I've had success getting traffic to my website with yahoo answers. If you are not careful in answering relevant questions that match the content of your site though, you can get your answer deleted and if you are a repeat offender you can be banned.
Yes I agree, spammer pops up very fast on Yahoo answer, but its still work for me to bring traffic Do you ppl have list of another great Q/A sites?
