Not sure how effective google pluses are, but I don't think it can hurt. I hope the thread is not off-topic or against some rule. I think its black hat. Basically, I want to exchenge google pluses with people. If you +1 my website MY WEBSITE I will do likewise for any site you want. If, like mine your site doesn't have a +1 button, just post full web address here and I'll search for it in google and the first result will have the plus button next to it. List your site here!
