I tested Threads. In my experience, this is how Threads compares to Mastodon:

— The algorithm decides if your content is visible to others. Some content gets zero exposure for reasons which are not transparent.

— Sharing links to other platforms makes the algorithm suppress your content's visibility.

— Slower to use.

— Only one app allowed, and it does not support iPads and other tablets.

— Ads are coming in early 2025.

— You cannot run your own server.

— Your data is mined by Zuckerberg.

@randahl but Mastodon doesn't have an algorithm at all, and your post is visible mostly to your subscribers, so you can't get viral.
@BigCaddy I have written posts with 1000+ boosts. That is plenty enough viral for me.
@randahl they're already your subscribers.
@BigCaddy that is actually not the case. What happens on Mastodon is, followers boost your content, then their followers boost your content and follow you.
@randahl @BigCaddy Engagement feels way more organic on #Mastodon, people with genuine interest and therefore a more robust community of followers and their followers.
@randahl @BigCaddy that's what I like about masto, no shady algorithm
