I was guilty of this when i first opened my account - read posts but would often skim through them quickly and leave a short comment. Then i realised how little the $0.01 vote matters to me in comparison to the time it takes for someone to sit and write something from scratch. Now im more grateful for posts i read and being able to read them myself :)
Maybe there are bots here purely to make money, but we cant hate them for it. So, I think youve found a nice middle ground there Jeezzle!
