I can't say I come across those over rewarded posts, but then I try to avoid looking where I might find them. 😆 I hope they aren't so prominent that new users see them much.
The best part of posting, for me, is the comments. Just love coming on to all those interactions and it's disappointing when there are none. It can be draining when you've spent half a day curating, though, trying to get a tired brain in gear to add a thoughtful comment.
I think a few more curators are targeting the curation posts lately. It's a good way of spreading the curation goodness, when you only have a limited amount of VP. Build the accounts that curate and reach that bit further. A few people are working on building that middle class to even the odds a bit more. That's something else Joshman has been working on, creating more dolphins.
