Linking to Lemmy image posts is a bad experience. This use case needs to be much better because content is the main way that non-Lemmy users can be motivated to join Lemmy. I tried to share this with a friend yesterday, and had to explain that the image I actually wanted them to see is locked behind a tiny thumbnail, and that the full size Good Place Janet someone commented is not what I wanted them to see (at least not without the context of the posted image).
There’s no way to open a shared Lemmy link in your client of choice. You can manually add URLs on Android, but you have to do that for every Lemmy instance, so that’s not going to fly. I don’t know if there’s any solution at all on iOS.
There’s not a good way to control what content I see. It’s essentially either “everything” or “a single community”. On Reddit, you could already have multiple communities about the same topic on Reddit, but usually one was dominant, and you had multireddits to save you if there truly are a few good related subreddits. Now on Lemmy, you multiply that problem by N instances, and subtract the multireddit feature. This situation simply must be made better somehow.
