This is treading on dangerous turf IMO...
Some folks still experience SCN as a resource they primarily want to use and contribute to for nifty useful things they want to share. Make contacts that way with people who like it and have interesting discussions. They want to learn and do clever things and use SCN as a medium for it.
That it is occupational therapy for the bench and an "air bag" for insufficiently trained call centers has not been realized yet by some contributors I know.
That some folks dont want to share knowledge and just like is omni-present and perfectly OK to rate the content based on likes.
But many knowledgable folks don't stay for long or contribute because they have more than enough work to do and easily don't find anything particularly clever on SCN anymore because of all the noise from the points system.
Just bolt the points system and give search preference to likes. That will sort it out.
-> no points, like weighting, status of the asset and a decent search on it within sap.com.
Who would want anything else to use SCN and contribute to it with useful information only?
Cheers,
