For all new (and "new" users), if you don't like the default Mastodon user interface, you don't need an app, there are web-based alternatives, here are a few I've been using…
**Elk.zone** - https://elk.zone
**Phanpy** - https://phanpy.social
**Sengi** - https://sengi.nicolas-constant.com
Each has its own strengths and weaknesses, test it out and see what works best for you! Or you can try **Firefish **(https://firefish.social).
@BOOKidealist It's under "# Explore" (in the sidebar, on the left), then under tab "Tags". It's the same in both Elk and the default Mastodon UI, just named differently, Mastodon UI calls it "Trending now", but if you open that, it's called "Explore". 
@elkarrde Thanks for this post Neven. It's a journey that I've been on since joining Mastodon this week. For the web (I prefer web over native on my MacBook!), I actually really like the official MD app. Took me a short while to get used to it, but I kinda dig it now.
@beecham I've been using them all, some more, some less, and yes, agreed, the official web is actually quite good! I love the sheer possibility of having to choose - usually, that's not a given.
