I think it makes sense.
In a blog post. The post is the focus. Likes reflect who likes the post.
A discussion has a different role. It's not " a statement with comments". It's an ongoing discussion. The likes downstream reflect that.
There are other differences between posts and discussions. They reflect the difference in nature too.
You also have Documents. They have yet another lifecycle.
ralphjy Interesting observation. How did you realize this?
I mean... with almost 50,000 points to your next level, I'm guessing that you're not putting a lot of time into trying to maximize you points each day.
I'm intrigued why we notice some things and not others.
kmikemoo - sometimes when there is a topic of interest to me, I'll click on the like counter to see who else is interested.
A recent discussion that you participated in - Insight why display fails with buffer board had 46 likes, but only showed 4 of us that had liked the topic. Anyway, just caught my attention enough to think about it. I guess it was a rousing discussion .
I never noticed this before, and it may be the correct behavior in context.
For Blog Posts, the "Like" counter just counts the likes on the main post.
For Discussions, the "Like" counter also counts all the likes on the comments.
Not a complaint. Just an observation...
