I did not said that Hive is a blogging platform.
Just that nowadays the most people use it that way.
Development of games is also going to fuel the chain.
It is already fueling. For example Splinterlands. That game alone should greatly contribute to the successfulness of the Hive blockchain. Games like Splinterlands should get more exposure. I started playing it on 2018.12.30. It was Steem Monsters back then. And it was on the Steem blockchain. The game later became Splinterlands, and later moved/switched to the Hive blockchain.
For the most part Hive is a blogging platform and that's about it. It's all the tribes and other things being built on top of it that hold the real value. Was around since alpha days of splinterlands. They branched out to other platforms such as wax and bat etc in order to reach more people. I'm curious to see what comes of Exode which is a new game getting ready to launch that will be exclusive to Hive. Being exclusive to Hive I feel brings more "value" to the hive token itself.
With the various dApps, games and websites, that seems to be changing. At least from the traditional blogging side.
For example there is d.buzz, which is a Twitter-like microblogging platform. There was also musing.io, which is a Quora-like Q&A (Questions and Answers) platform. Musing still exists, but nowadays it is using its own blockchain (Musing Chain).
There was d.tube, which also still exists, but nowadays it is using the Avalon blockchain.
If the other dApps begin to use their own blockchains, then the Hive blockchain will probably really remain as a blogging platform.
