Ask HN: Many of You Use Linktree and

They seem to be used by people who generate most of their money from some platforms, but want to be visible on others. Corporate social media often limits how many links you can have in your bio, and often limits what you can link to (eg. online sex workers can't link to their smut from everywhere, or will have their posts suppressed if they link to smut, but can link to link aggregators which link to their smut). I think their core user base is more like "influencers" and "makers of controversial art" than "Hacker News posters" because most Hacker News posters have a day job or a business.

They overcome limitations of most social profiles not being flexible enough. Kind of useful but easily made obsolete once said social networks improve things.
