I don’t use the official app. However if you would like to try out Ice Cubes that would be another fully open-source and free as in beer and speech app which has trending hashtags, trending posts, and suggested users in it’s search tab.
The algorithms it uses are pretty simple and fully auditable. I think it’s mostly just tags with the most posts in the 24 hours etc. Discovering important news like back in the days on Twitter works the same with this feature.
