I recently read somewhere that only 1 in 20 is active in the social space, most are lurkers. And I think personally it might be a lot less.
So if you are a lurker reading this, start to become active! Start upvoting good stuff. If you have a bit coin, give a little to the peeps mentioned it the article. It makes such a difference.
I am the author of this piece and I should have mentioned joining forums as a Nice activity. I have also recently joined some forums and tried upping my participation levels. Some forum users can be prickly, it is not all roses, but so long as you avoid the drama it is a rewarding experience.
