Is this the same thing as about.me?

I signed up for that 10? years ago when I saw it on hacker news [1]. And that was apparently just a clone of flavors.me

Are these just sites that ask you to enter a ton of personal data so they can sell it?

Or are people benefiting from this? More than a LinkedIn or Twitter or Instagram or wix or Google site or free hosted WordPress or medium?

I had an idea for a site sellmyinfo.com where you enter your info and I'd split the profits of selling it with you. Maybe that idea has wings?

[1] I must have seen an article 4 days before this, but "about.me" is hard to Google for https://news.ycombinator.com/item?id=2025764
