<minor rant>PerlMonks is set up to provide discussion threads. When you carry on the discussion by simply updating the original node, instead of following up to the individual followups, it puts me in a position of not knowing whether my subsequent follow-ups should also be created as updates to my post, or as additional follow-ups to your original node. In other words, you create confusion when you try to add something to the discussion in a way that circumvents the discussion-thread format.</minor rant>

Now for the purpose of this followup:

I wasn't trying to say that unlimited voting on a node would screw things up (certanly it would). I was (probably ineffectively) trying to convey that even the potential for a double-vote on a node would be improper. One vote per person per node, that's how voting works. No voice is more important than any other voice, with regards to the reputation of a given node.

And I'll reiterate; the personal touch of a /msg is a lot more meaningful to most people here than an above-average node rep.
