Because it isnt, really. Slashtags was an attempt to build our vision using hypercore, we scrapped that design and made Pubky instead. It took us 1 year to make Pubky. This is a the product of the hard work of a dedicated team trying to help users. If you want to learn about new things, we have lots of info about what makes Pubky different, but we also understand people feel loyal to their social media protocols, and might prefer to discredit us.
