In my short time here, I have noticed there is a fair bit of free riding happening. This problem is common everywhere. I think, however, it can be demoralizing for some people when they put a lot of effort into a post, but then it does not get any upvotes--or just very few upvotes.

The strength of a community such as this is that members can help each other by upvoting each others posts. I always go through my friends list and upvote their posts.

Why isn't everyone doing that?

Members, perhaps, need some easy to understand information that will encourage them to upvote others.
