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.

Keytrace might not be much on its own, but as part of the greater Atmosphere, it is welcome infrastructure for building and verifying an identity.

The best package manager interface I've ever had the pleasure of using. Every single feature is carefully designed and implemented. If 'premium software' is a thing, npmx is it. The supportive and ever-bettering open-source community around it is perhaps its greatest asset.

Tangled might not have all the bells and whistles just yet, but it is a solid and reliable Git forge with a good foundation.
