My $0.02.
I like the new more prominent “like” button as I think it’ll encourage people to express their opinion. On the old site, the “like” option was very small, so it was very discouraging to spend time adding updates/stories/encounters to the forums and yet seemingly no-one liked them. So I gave up.
As for a “dislike” option, I thought it was useful as there are some recent forum updates which I definitely would have “disliked”. But it’s your site so do what you want to do.
A further $0.02….it’s looking good so far 👍
