I think you can remove the word "by"
We are having the same problem on how to show it correctly on GraffitiGeo. We ended up using "by ivinkirigin, points: 10", which in my opinion is still not perfect.
Any idea on this?
If the numbers are changing you get accustomed to it quickly.
By the way, my original comment has an absurdly high karma count. I think that is a direct result of hiding the count.
I don't believe I've seen a site where any user can give more than one vote, so I don't think this is misleading. But I've not thought about it before, and I do like "by ivinkirigin, points: 10" better.
Kudos on putting so much thought into your UI. Definitely bodes well for GraffitiGeo.
