2/ What type of content (and how much) is currently on nostr (topics, formats - short text, long, images, videos, podcasts, etc). Is there a good site where I can get some stats for most popular relays?
There's an API from nostr.band (not affiliated) at https://stats.nostr.band/stats_api?method=stats that shows what kinds of content are being used and when. For example, daily.datasets.kind_0 tracks how many user profile events (kind 0) were found across various relays. The data looks like this:
    {
      "d": "2025-03-15",
      "c": 36349
    },
3/ If you could get NOSTR-reader custom made just for you, what would be the interface? How would you like to tell the app what content you wanna see? No stupid answers, the more creative the better.
the client I personally want to use is what I'm building, an invite-only private community focused nostr client
