Just selecting the best response?

If you really have nothing to say, so what can you say. But yes, don't forget to select the best response. Sometimes, I just select the best response too and give to each one of those who respond the positive rating in gratitude to spending sometime to respond to my discussions.

I think that will do, if you really have nothing to say and just to say thank you is not appreciated by admin (it may not be a violation but definitely, it does not earn). Sometimes I just choose the best response also.

just thanking will not increase your earnings.It is not meant that we should not thank.Dont just thank the responder.You can add few words about their comments or if you contradict them why dont you post your views.If nothing is there then obviously you can select the best without giving any comment.but dont forget to give the best.

I think we can especially if there are many replies. Just select the best response and what else would you do if you really have nothing to say. It's very diffifult to be writing nothing.

I generally just choose the best response. I dont thank them. Sometimes I thank someone who has given me a best response though.
