Hello!
Interesting questions you bring up.

Regarding my favorite frontend, I miss an initiative I had that motivated those who interacted the most.

I'd like to see it integrate the ability to make posts where videos and photos can be displayed at the same time.

As for what my dream frontend would be like, I really can't think of anything right now, as I'm still processing this wonderful world.

As for why I use it, well, it's simple; having an app provides more operational options when approaching it.

There are others I like, but without apps, they seem limited.
In particular, there's one I really like, but when I try to write posts there, the preview doesn't display properly, and that discourages me a little.

Regarding the CryptoCompany frontend, I'm not familiar with it yet, but from what you're saying, it seems like an interesting option that I hope to try.
