Impersonally, I still think answerey3 is the best yahoo answer tool AFAIK. I am happy to use it to auto-post 300 answers everyday.
And yes, the posting speed is not fast, about one post per 1 minute for me, but the speed is acceptable by me, because it is auto-post, I just leave it to run whole night.
The only not good is that I have to use proxyfirewall to load my private proxies to work with answerey3, hope the developer can build the function in the software.
Fucking love the traffic from yahoo answer, and also want to try more yahoo answer softwares if anyone know.
