I've been on the StackExchange boards for quite some time now and it seems that people don't upvote other's answers anymore when browsing the site. At least from my experience.
Let's take this example. When I answered this rather simple question it had 3 views. It had 30 views and not a single viewer upvoted my answer although I think it basically answered the question with links to two related articles for more information.
In this other example there is a clear and simple answer that would - imho - deserve an upvote.
Note: It's not about that I demand reputation for that or anything, it's just an example. But an upvoted answer would at least get the question out of the "unanswered" tab.
So my question is: Shouldn't users be encouraged to upvote good information whenever they see it? At least that's what I like to do when I browse other topics, even if I don't understand much - a useful answer deserves votes, not just by the OP.
