- From the Official Documentation:
- Top Stumblers are the most active and helpful community members. These members frequently suggest new sites to be included in the StumbleUpon database, and frequently rate new sites they stumble upon. When you submit a site, it is shown to other stumblers for evaluation. If those people like your suggestion (by giving it a thumbs up) your community 'Karma' will increase. Your Top Stumbler rank will also increase by frequent rating. You do not need to rate every site you see, but if it stands out as particularly excellent (a website you really like) or bad (you don't like it, or it is spam), make sure you rate it. This regular participation will increase your Top Stumbler rank.
