Yeah... you gotta post more LOL.
You should follow at least 300 people or this place is "dead" WHO those people are determines if it will be "fun" ... but it's easy to unfollow people and no one is offended if you do so I'd say follow liberally...
Also write an intro post and put hash tags in it. What you see here is based on who you follow and the tags you follow. You have more control... but that means you need to say what you want to see.
