I created a invite code for HN, so you can sign up without wait; https://getkozmos.com/signup?code=HNEWS
Here is some brief info for HN users. It's built on Go, Elastic Search and (Pr)eact. The extensions use IndexedDB [2] to create a database [3] that users read/write, and that database gets synced with Kozmos servers. This makes Kozmos' like button work consistently, even when Kozmos is down or user has bad / no connection.
How will Kozmos monetize ? Kozmos will always be free for bookmarking privately. In the next version, I'll introduce public collections which users can use for creating nicely organized bookmark collections, and this feature will be available for only paid users.
For more details, I wrote a blog post; https://medium.com/@azerbike/introducing-kozmos-a-new-bookma...
Thank you,
