I don't think much upvoting is happening right now. Of course there are only around 80 questions at the moment, but if you look at Badges page statistics, it's not quite positive:
- Of 400 users, only a little less than 100 have earned the Supporter badge, meaning having done their first upvote;
- Less than a handful of users has a Suffrage and Vox Populi badge;
- Only 4 questions have scored 10 or more, also only 4 answers
Just sit down and take some time to browse through questions and spent your upvotes. Of course don't go upvote blindly. Always keep looking for quality and reward that quality.
Much upvoting will motivate beta participants and will stimulating a good upvote culture which contributes to a healthy website, now and in the future. Much upvoting will also create more high reputation users, who will have more privileges and thus more people to contribute in moderating the website.
To everyone reading this, there are some rules to voting. As I already mentioned, don't go vote blindly. Also do not vote on all the Q&A's of one user (like open up their profile page and vote on everything), because serial voting on a user is not allowed and will be corrected, see this answer below.
Pick a topic/tag you are interested in and upvote quality Q&A's and downvote poor ones.
If you would downvote, a question or an answer, then leave a comment! Leaving a comment will help the asker or answerer to improve and learn, which will increase the overall quality of this SE. After any edit of the question/answer you are allowed to change your vote: undo the downvote and maybe convert it to an upvote?
