I keep seeing this as well. Probably the most frequent ad I’ve seen.

After a day of use, I’m incredibly disappointed.

The fragmentation problems, and lack of cohesive community discovery (or even apparently any agreed standards for sharing communities etc. across instances in a way the most popular app can reliably recognise as being a community and not an external link or mailto address) will make Lemmy an absolute non-starter for 99% of potential users.

I’m sure there are solutions, but as it stands I can’t see Lemmy gaining any widespread adoption without a significant leap in user friendliness in regard to how federated instances are implemented and managed.

FYI, clicking those links in the Jerboa app on Android attempts to open Gmail to send an email.
