I really like some of the features hinted in the profile mocks. As a quick background: some of my points from this SN comment would still apply here - so please take a look there.
I think some users would be interested in making the SN profile page their "internet profile" page.
Specifically I think as a user it would be great if I can select couple building blocks for the profile to make it my own. E.g. I would like to select following blocks:
links to other accounts (e.g. nostr)
my markdown fullpage description on top.
show my top articles (not shared links) - exactly how I currently have it in my SN profile.
show my top SN comments based on zaprank
show my Nostr comments and have a convenient link to open those in the right nostr app...
It would be for sure good to have a solid default. Defaults matter.
I think the stats and trophies are ok, but in the mocks those currently take too much space - I would like to have those somewhere on the side, I'm more interested in having my content and links in my profile page.
And just one quick point to keep in mind:
Separate Public vs Private: Clearly separate the "public facing profile" view from the "user private config/wallet, etc" views, so users don't get confused.
REDESIGN & STYLING
For the redesign & styling: I'm not a fan, since the design "language" is what we used to do in early 2000s and not in a good way. This was the style before we discovered "flat UI design" in 2011+ :) (this is a reasonable summary). The color gradients (yellow to orange) in the buttons/logo is what gives it away the most. Font sizing, font face, and overall spacing is also not that great, but that's not as hard to fix. I'm definitely not against redesign/updated styling, but I don't like this one in particular. My tip would be to share it with the best UX designer you can find and get their input/critique.
