Jera Value@Jera_ValueThere’s always one last push toward perfection ·

🕯️ There’s always one last push, one more step toward perfection. A lot of people stop at 90%, because that final stretch is the hardest and comes when we’re already exhausted. But that extra 10% is what really makes the difference. The gap between good and extraordinary

Jera Value@Jera_ValueHow do Community Notes work on X? ·

1/ The algorithm of truth — How do Community Notes work on X? They’re those notes that show up under some tweets to clarify or correct information. The interesting thing is they work surprisingly well. How does it all work? Let me explain ⤵️

  1. 2

    2/ It all revolves around an algorithm that measures whether a note is “helpful” or not. First, users rate notes as “helpful,” “somewhat helpful,” or “not helpful.” Then the algorithm uses these votes to train a model that evaluates both how helpful the notes are and the “quality” (or trustworthiness) of the voters. 🧠

  2. 3

    3/ But votes alone aren’t enough: you need cross-partisan consensus. That is, support from both left- and right-leaning users. If there’s no agreement between both sides, the note isn’t published. 🤝 This consensus acts as a quality indicator: if it convinces everyone, it’s probably reliable information.

  3. 4

    4/ Also, your influence depends on your track record. If your votes tend to align with the consensus, your weight in the system goes up. If you’re always disagreeing with everyone, your impact goes down. This prevents biased users from distorting the results. 🎯 (Obviously, this isn’t risk-free)

    5/ Abuse is penalized: if a note is marked as offensive by cross-partisan consensus, those who rated it as “helpful” lose credibility. 🛑 That way, the system discourages toxic behavior and rewards constructive participation.

  5. 6

    6/ Algorithm summary: • Only notes with consensus between left and right get published. • Reliable users have more weight. • Abuse is punished. It’s simple in concept, but it raises some questions: • Is this balance sustainable? • Isn’t reducing everything to “left” and “right” a bit simplistic? 🤔

  6. 7

    7/ In any case, the system is a fascinating experiment. It’s not perfect, but it seems like a good foundation for managing misinformation on large platforms. And realistically, it works pretty well in practice. What do you think? 💬

Jera Value@Jera_ValueA salary isn’t wealth ·

People are impressed by high salaries, but a salary isn’t wealth. I earn well, but I’m undercapitalized because I’m young. Someone older, with a lower salary but more net worth, can afford to splurge more than I can. Net worth >>> Salary.

Jera Value@Jera_ValueOver the last 4 years, I’ve doubled my net worth every year ·

Over the last 4 years, I’ve doubled my net worth every year. Just so we’re clear, it’s not magic. Going from zero to building something isn’t that complicated if you focus and go all in (especially when you’re starting with nothing) The hard part starts now: keeping up the pace in 2025. Let’s see if we can keep raising the stakes. 🎯
