So as you can see this is about LIKES...
I don't think there is any regulated protocol in place as to the frequency or usage of a "Like".
Just because I or someone else "likes" a thread/reply/post does not have to mean that I or another agrees with what was said.
Whenever someone takes the time to type a well thought out reply/response and communicated it in a very articulate manner, I think they deserve at the very least a like for their effort.
If it will make you feel better, if there was an "UNLIKE" button believe me, I would be using the crap out of that one too!
The reason I posted this in the first place is because apparently I "LIKE" replies/posts/threads too much.
