Noticed the spelling error, want to correct it but waiting to do a push until this fades off of the top page of HN. Thanks for pointing it out though!
As for the kudos mechanism, people seem to be happy to engage with it. I know on HN it's something that everyone recognizes but the average web user doesn't notice it (kind of like Bootstrap).
As of now this post has 67 points on HN and 782 on BlogMask. Means that people really must like watching that little circle fill up to vote. Not exactly "scientific", but definitely enough to make me leave it in as a feature.
