You are actually posting on the Hive blockchain. Travelfeed is one of the many ways you can post to Hive, imagine Hive being a house and travelfeed being one of the many doors that you can get into the house. The other ways you can post on Hive are https://hive.blog or https://peakd.com/ they are the main interfaces. You can access a lot more features when posting via these two interfaces and develop your network much more effectively as you are reaching a significantly larger audience. Building your network is crucial to get more support on Hive. At the moment, your content is barely getting any support as you are not actually involved on the Hive blockchain.
For videos you can post via https://3speak.tv/. They are like YouTube, but on Hive and offer a lot more support for video content creators.
You can access all these sites with the same username and keys. Which ever one you choose, they will land on the same Hive platform so please only post your content once, and not once from every interface.
