we all knew that there are many forums and some other discussion sites like yahoo answers,mylot, answerbag, wikianswer etc..
a) So, if we particpate regularly in these type of websites, do we really get benefit either backlink or getting sales for us?
b) which is better whether participating in forums? or in these discussion sites I mentioned above?
I hope most of the experienced ones already tried all these, so I need your suggestions...
waiting for your responses!
