No, the app is made for everybody who wants to use a messenger. Not just you and him. It's supposed to be under the standards of the feddiverse.
The comments here are not a poll. Providing especially personal comments about a nerdy user like me and the guy I replied about "I would like it like ICQ" and such shit, would not help the creator make a good choice. Most people nowadays, especially zoomers, dont even know what ICQ is or how it works or how to even login to it. Most people, proven by ehm ... the success of messenger, discord, whatsapp, telegram, viber, signal everything ... want a messenger that provides what the mainstream messenger wants with most of the features that everybody provides and are mainstream used while having ease of access.
We should try to help the creator. Not misguide him. Again, the comments are not a poll, they're supposed to help to make a constructive conversation. And when you talk as if the app is made only about yourself, you're not really helping.
