Speaking from a moderator's perspective, I would absolutely loathe having a "dislike" feature. Have the rabble already forgotten all the threads and posts accusing others of being "thin-skinned" or for whinging when something gets flagged to be actioned by the mods?

Tell me that people WON'T start complaining bitterly when their post gets "disliked" by someone... The mods would be continually policing this. Not something I care to spend my time doing, really.

As for having a "Like" or "***" or "Thanks" button, I'm relatively indifferent at this point. As Steve points out, the limiting factor might be whether or not such an add-on exists for the vBulletin software, but also, whether it can be easily implemented. Before our last major site upgrade, Steve was having a whole slew of technical problems because the previous owner had installed a zillion different mods (that's modifications -- not moderators) and add-ons, some of which did not play nicely with one another, or the forum itself. It was only because we moved to a brand new installation that this all got resolved. So I'm sure Steve is probably not just a little leery about potentially "breaking" the forum by introducing a new mod like this. Not saying it's not possible, but just pointing out that there is a technical side to this, that does cost time and money to implement...
