Liking a topic/reply and voting for an idea will have a varying levels of impact for each community.
Community Managers, like me, will want to incentivize/reward those activities differently.
Additionally, points for likes can lead to users trying to game the system by liberally liking most posts/replies (I’m seeing some of that currently). However, there’s no way to reduce/remove the points for giving a Like without negatively impacting Votes for ideas.
