This is an entertaining idea, but only that, IMHO. It really won't serve to create an air of importance or even consensus on any single post. The reason? Some individuals like to create many trolls/personalities on a particular board for various reasons. Therefore, using these one could inflate their own reputation without it actually adding anything of value.
Just being around and reading the wisdom of members is enough to know who're the reputable members, IMO. The newbs might not know right away, but it doesn't take long for them to catch on.
What other fun add-ons does this software have Shan?
