I don't know a single person who would come to Hive for any other reason than Splinterlands and even that is very niche. Via Splinterlands, they then might start blogging or try another app. But other than that, 99% of all people I talk to, have never touched anything in the blockchain world yet or even heard of it. Hive would be vastly to complicated for them. It doesn't matter at all how much comments are done here, new people would not even be able to create an account. Blockchain technology is still 10 years or more away from being widely adopted. Whether Hive will survive or not I cannot tell. I think the Social Media aspect of Hive is doomed. Using it for games and other apps, though, might work.
