Over the years the various incarnations of this forum software package - SMF - can include a "karma" feature.
I have never invoked the feature.
It's decisive, people voting for a post or topic, it's all too subjective and people will be upset if their contributions are "marked down"....
I think you meant divisive, not decisive, but I see that no-one else picked this up, so perhaps it does not matter.
I think it might be divisive if people were allowed to vote 'thumbs down' (people will be upset if their contributions are "marked down"....), but I'm quite happy for people to be able to say 'I liked that' without having to swamp the thread with posts saying only that.
I have 'found' the bookmark feature, and use it on an occasional basis, when the subject / response is of interest to me, or contains a nugget of information that I haven't seen before.
As a poster of mainly 'technical' responses I would appreciate some indication that an otherwise silent reader found my comment useful. There have been two recent examples, when a single person, sometimes the OP, has written to express appreciation of a response I've made. I'd be interested if others thought likewise; sometimes I've thought 'why did I bother?'. I think that people not bothering to respond lowers the effectiveness of the forum.
"
This version of the forum allows YOU to ignore posts made by a user (except admins and moderators) but forum users don't know they are being ignored.".
I have also started to use this feature in relation to 3 or 4 users, just for my convenience.
I agree I wouldn't bother using the feature if it was revealed to the ignored person, because that revelation would be divisive; I'd rather walk away completely than put up with the brickbats that would be thrown.
Regards.
