Many people come online to post things they want to share with friends, family or the world, others just want to edit other people's stuff.
When I say 'edit' I mean it in a cynical way. I'm talking about those who are always finding the errors, the negatives, so they can point those out.
Listen, if you going to come on funbook-pk.com and post nothing, then you are not contributing much. I'm sure your pressence is appreciated but your input would be so much, more valuable.
Create a themed page or group. Add things. People will like and comment on. Or, like other people's posts, comment on them too.
A great social media site depends on it's members to make it so. Make funbook great.
