Most of the time I post what I like, put my opinion across, make jokes/sarky comments etc... I dont really care if people enjoy my posts, but if I feel like I can add something to a discussion or help and share a bit of knowledge then I will.
I've thought before that the sarky comment thing is a good indicator, some members will seemingly piss themselves laughing at average comments made by 'in-crowders' to win favor and be accepted into the circle of trust, but other sometimes funnier comments by random members here and there are just passed by.
Its kinda sad, but at the end of the day, this is the internet.
Cheers,
Grant
