There's a ton of what I would call "hobby" bloggers here on hive that write about travels and such and get voted out of the woodwork. Issue with these is they simply wont rank and drive traffic nor are these people sharing their blog post on hive with other social networks to drive that traffic and engagement it just sits all on hive.
Many of these hobby bloggers also take their rewards and sell them out of hive which I mean is ok but it's just a constant drain on the hive price when that happens. There are many MANY more factors that should be considered with curation and curation trails but are either far too hard to track, too time consuming or any number of the above things.
Will we get there? I'm not so sure... However I will say I believe we have gotten better. But there's always room to learn, grow and improve and that's something we all should be open to.
