It's been awhile since I've been on here, and to my surprise I saw a like system on the forum threads. At first, I didn't give it much thought, but I'm not sure if this will be beneficial in the long run.
A like/dislike system is flawed whether it has likes only or dislikes too. Seeing social media (Facebook, Youtube, etc.) with likes only and sites with likes/dislikes (Reddit) shows that likes are frighteningly capable of manipulating people easily. Many conversations on here become polarized very quickly reason why I took a break in all topics, and in all honesty I'm not sure if a like system is what the site really needs.
If a like system should be implemented, it should be on the original post only. Users should like/dislike threads they believe are high quality, and similarly to Reddit it would push threads deemed higher quality upward. It would promote an increase of quality in all posts, and avoid threads deemed baiting/unneeded/etc.
Granted, I haven't been on here for awhile, and I don't want to place too much weight on my opinion. It's simply something I thought was worth discussing
