Using Mastodon: hashtags, etc.

I recently wrote a blog post about Mastodon (in Dutch). Originally, I wanted to include this information there as well, but it became a bit much. Besides, this lends itself well to a separate post.
I wanted to show how I use Mastodon, because it can be difficult to truly make such a new medium your own. It took me some time, in any case.
Following Other Users
Once you’ve chosen a server (or instance, as Fediverse servers are sometimes called), you can get started. The first step is to follow interesting users, and here you’ll find a nice list of Dutch users who are worthwhile. You can also follow me, of course. I talk embarrassingly little about classical music (but just you wait, I have things planned!).
Hashtags on Moshidon
But then: where it really gets interesting is the hashtags. I personally hardly ever look at my actual Home page; what I like is following hashtags. The Android app Moshidon works very nicely for this.
This is what Moshidon looks like when I open the app:
![A dark mode screenshot of the Moshidon (Mastodon) app's home timeline. The top post is from 'Asta she/her/they' and reads: 'I use PDF patterns rarely enough to always forget how much I hate putting them together in between. They're the worst. But then again so is copying patterns so I guess it's just patterns in general that are the worst! #sewing'. Below it is a post from 'Benita Skinner' that says 'Good morning ☕ Say hello, if you're my neighbour... 👋 🥰 Happy Stitching! ✂️ 🧵 ❤️ #quilting #sewing'. This post includes a vintage image macro showing two women sewing, with the text: 'When working on a quilt, I'm in my own little world. You know where tha[t] you're my'.](/images/blog/2025/Mastodon-hashtags/Homepagina_Mosh.png)
Nice, it shows my tab with a collection of hashtags related to sewing. I find it a relaxing and creative hobby! The Great British Sewing Bee is totally my jam! Note that I don’t see the regular home page. Maybe there are posts about the current state of affairs in the world there, ugh. I’m not always in the right mood for that.
If I swipe left or right, I switch tabs. If I press ☕ Naaien ⌄
in the top left, I get this list to manually select the tab:

I have a lot of them, but that’s okay. Usually I don’t even use this menu but just swipe to the next tab when I’m done with it:

To create this, press ⋮
in the top left:

Then on Edit timelines
. You will then see a list like this, probably only with Home
, Local
, and Federation
. Here you press +
.

Here you can set an icon (1) and the title of your tab (2). At 3 you enter the main hashtag, and at 4 you can add extra tags. Not at 5, otherwise you will only see messages that have both the tag at 3 and the tag at 5, and not just one of them. With 6 you can optionally filter out certain hashtags. For example, for my “Crafts” tab, I don’t want to see things about sewing, because I’ve already seen those.

Et voilà, you’ve added a tab!
For me, this is such an important feature that I actually can’t use most other Mastodon apps, as many do not support this.
Hashtags in the Browser
This is also possible on the computer, although in a slightly less elegant way, if you ask me:

This is the “Advanced Web Interface”. If you click on ⚙️ Settings
on the website, the checkbox to enable this is almost at the very top.

You then get a column overview. If you click on a hashtag, it opens a new column:

By clicking on in the top right, the button to pin the column appears (with + Pin
). If you click on Include addition tags for this column
in the newly created column, you'll see a similar menu to the one in Moshidon.
Then you can horizontally scroll across a large page with all the hashtags:

(Tip: Hold down Shift and scroll with the mouse wheel to scroll horizontally!)
I would have preferred a menu with these kinds of hashtag collections, like in Moshidon, but hey, this works too.
Hopefully, this helped!
Until next time,
