Why do these forums have both "Like" and "Helpful" buttons?

[ClayUUID]

As the title says. These are primarily support forums, so overwhelmingly any time I like a post, it's because I found it to be helpful. But I assume Adobe had Very Good Reasons for implementing these two seemingly-redundant buttons, so whenever it does occur to me to use them, I worry that I'm using them wrong. Since I dislike both worrying and doing things wrong, as a result I pretty much never use either of them.

I would guess that it's to mimic social media websites.

I know the "Helpful" button actually adds to someone's score on the forums.

Did that help? If you think I'm helpful, you can click that little button!

Since Adobe rents the forum software from Jive, I would guess this question is really for the Jive programmers... who sometime seems to be trying to emulate Facebook

I can LIKE a response for a lot of reasons.  Maybe it was funny.  Or perhaps it said something the OP had not asked about.   But is it HELPFUL?  I don't know.  You be the judge of that.

Correct Answers are usually awarded by the OP.  Or sometimes a moderator will mark a Correct Answer even if it's not THE Correct Answer.  That's where HELPFUL can be well... er... helpful.

Nancy, I liked your response, and also found it helpful. Took the words out of my mouth.
