Pardon my ignorance, but is Atlassian a good example to follow?

So basically anything anyone who is building at that scale would have some rendition of? I hate these LinkedIn wannabe “I got the latest expert scoop for you” style tweets.

Its like someone at Discord being fired then telling the world they worked with Erlang and Rust to scale Discord and some rando on Twitter saying “anyone can now rebuild Discord!!!”

This is absolutely worthless. It's not hard to build a similar system, there's no moat in that. It's growing it and operating it that is difficult.

All this guy accomplished is making himself unemployable.
