It's a great written article. I still don't exactly understand why BlueSky perse had to build a Twitter alternative as the author nostr:npub1f4faufazfl4cf43c893wx5ppnlqfu4evy2shc4p9gknfe56mqelsc5f7ql states. I think that's something I agree with nostr:npub1p7fw7hcnf2sff3gvjjxdxc8utfr4fg3qvh5jedgffe6ggjczdh8ss7vf3w. They better focused on building the protocol. Now with the protocol and the service (bsky.app client) it will face the same problem as happened to the mastodon.social instance by the founder of Mastodon Eugen Rochko. It's kinda the same problem we see nowawadays with the biggest relays coupled to the most-used clients like Damus, Primal and Snort. I predict many new bigger relays will popup in the future coupled to yet to be build clients with unique killer features. 

My love for Nostr is still the strongest. The most open, easy to use and community built protocol. We're very very early. Both protocols are walking their own paths, so I rather not try to compare them. I don't like to 'fight' or debate too much on these topics, as we're all following the same purpose on the long term. Just let us build the change we would like to see.
