Fully agree.
I'm one of those people who migrated to tumblr after the Reddit exodus (tbh I did have tumblr beforehand, but my usage increased a lot when the API bullshit happened). After using it for around 10 months I've come to the conclusion while yes, it is good for fandom related content, memes and some other things it's simply no replacement for reddit (it's actually more of a replacement for my fandom instagram to me). Yeah you can follow hashtags or topics, but tumblr is too niche of a platform and a lot of the topics I care about the average tumblr user doesn't even think of, or at least not to the extent I do.
If you want a reddit replacement Lemmy is simply your best option. If you want a Twitter replacement then yeah, go ahead and use Mastodon.

You can also use Friendica if you enjoy Tumblr. It has a wider degree of customization in regard to its interface, and you can also cross post or get your Tumblr feed in Friendica (provided the server you're using has the appropriate tumblr addon).

That looks really promising, I never heard of that before, thank you for telling me! Do you perhaps also know of any unofficial tumblr android app that lets me add two accounts/main blogs (ideally FOSS, but I'm willing to make compromises)?
