Firstly, thanks for including me on the list. It's very much appreciated.
One thing to mention is that by removing the 'steemtank' tag it means it will vote on any contribution I make on Utopian (whether that's development or not), to any project, not sure if that's what you want that seeing as it may or may not be related to Steem. Got the impression that you want to reward quality brought to the chain so just wanted to mention that potential and as I regularly contribute to Utopian on a few projects I don't want the VP to get wasted on contributions that don't meet your goal :)
I see what you mean. Do you have an alternative?
The goal is not to reward only contributions per-se, but the contributors. Imagine something similar to patreon.
PS: The vote you received was due to me forgetting to check for top-level posts. Fixed now, but you can keep the vote.
When my nomination comment got a vote too, I guessed it was that.
In terms of an alternative, why did you drop the 'steemtank' tag? I quite like the idea of being able to view a feed of quality development contributions from selected authors? At a guess, it's to improve ease of access. In terms of rewarding contributors over contributions I guess the current system works, potentially you could combine utopian tags and only reward certain categories, but I guess value could be provided in any category. You could go the other way with a no vote tag, which would prevent the vote, but again from a UX experience that isn't perfect.
With all the above said, I guess it's not much of a worry at the moment with the current vision, just being wary of your SP if it was an issue :)
