I agree that a 'helpful' button would be nice, certainly much better than a 'like' button. To be really useful, what I'd like is a way to view a thread with only 'helpful' posts visible. This would be tremendously useful when searching for information. Far too often, a search returns some threads with many thousands of posts. Very likely the desired information is buried there, but it's far too much work for many FTers to read through the entire thread, or even the posts returned by a search, to try and find it. If there was a was to only view the 'helpful' posts, it would be much more likely that people would view the thread and see the information.
