Sifa quickly became one of my favourite atproto-based apps, because it really makes a lot of sense to provide a professional ID on an open protocol where everything is public. The fact that it (optionally) populates my sifa profile with my activity on other atproto apps I use (such as when blogging on offprint) is sooo cool. I really hope it takes over LinkedIn one day.

Sifa is the best place to maintain a professional identity outside of a personal website. It is made perfect by being part of the Atmosphere, so you're not building your network from scratch. Beyond the network benefit, being part of the Atmosphere means that your profile is not a maintenance burden and instead updates itself by pulling in the information you choose from across the network. If you're looking to ditch LinkedIn, Sifa ID is the place to be.

@sifa.id Little _bug_ report I think: My verification email is not arriving in my inbox (I checked spam xD). Maybe you use some regex to unintentionally not allow <name>+<tag>@gmail.com e-mails? It's not a convention or standard, but should probably be supported for all 1 users: me 😊

I prefer this approach because people may *want* different profiles: @sifa.id may be too formal @babesky.com may not be age appropriate @tangled.org may be too technically oriented …depending on *your* product. The approach above lets *you* choose what order of preference, and which to exclude ☺️
