Sure thing, that's why we offer two different editors!
While markdown and very basic HTML is usually not an issue since it is very limited in formatting options, the problem with HTML on Hive is that it doesn't look consistent on different frontends, even between hive.blog and Peakd there are many differences and mobile apps sometimes have completely different formatting. Even though our rendering code is based on hive.blog and aims to be consistent, formatting can in some cases be different on TravelFeed.
