From time to time, I remove the VOTE option from some Forum's section(called Categories in Discourse) as it has no use... And if the Vote option is ON, we can't like a TOPIC(post)...
Feel free to bring them back if you're in a Category that would benefit having the VOTE option turned on.
Well, the Vote feature is a good thing to have for things like Howto's (people votes the most liked howto's, so they can appear as a preferenced order), similar for voting about suggestions or other similar things...
What is true is that we are only a few active users (a bunch of 10 maybe?), and this is of course not enough to make it really useful (threads with votes could have 1-2 votes, but most of them has 0), so this feature should be much more effective if we have more amount of users
Then we can talk about a problem: how to bring more people to the forums?
