Here's my take on this matter...
1.) A public poll seems fair enough. (This will give others a chance to have their say, too.)
2.) Personally, I've always wanted the option of choosing either one or both buttons ("like or thanks") when needed.
3.) I don't think that most members are even aware of the "like" button because of where its position. If the decision is made to keep this feature _ then I would suggest placing it alongside the other buttons below.
4.) If it is possible, could the notification be disabled? Why? (Reason): I don't want to assume that the notification on my profile is indeed a confirmation from a liked post and not a private message or a friend request.
5.) It would be nice to have the "likes" and "liked" beside our posts. (If not both, then preferably likes).
Overall, I would have to agree with what Phases said,"I really think the benefit of being able to jump to high liked posts will prove worthy."
