Ah. Gotcha. I see where we got cross-wise.
anyway, 3 out of the 5 people who upspoked mk's "pics or it didn't happen" comment ... were at that meet up. that mk's requesting photo 'evidence' of. and the other 2 are close friends with people who went.
As a database developer, I was thinking about the upspoking as a way to bring content to light to people who might not otherwise see it. You know, helping good content show up in chatter, etc., because it has been deemed of general interest to a wider audience.
I was thinking of upspoking as an invitation to the larger audience to participate/read content that they might not otherwise see.
I get your angle on it too, but I think your use of the hubwheel is more of the Reddit/Facebook Upvote/Like use... you are giving an "atta-boy" to the poster for their participation in a specific thread.
From my perspective, I look at each post and comment as an empirical thing in and of itself. And then I think, "Is this interesting to a larger audience? Do more people need to see this?" If my answer is Yes, then I click the hubwheel.
On the other hand, if - like you promote - the intent is to thank/recognize a good comment/post, I'll instead make a comment to that effect. That feeds the need to recognize someone for their participation, without peeing in the larger pool of data, and potentially burying "good/interesting" content from being seen by others.
Thanks for digging into this with me. It just helps reinforce my initial thoughts, and makes my post even more relevant.
