Did you know it’s National Wikipedia Day!? We aren’t quite hype enough to have a Wiki page yet, but we dreamed up what ours might say if we did have one! What do you think? 🤗🤗✅✅
 
In actuality, Wikipedia pages aren’t just handed out like free chips at a Mexican restaurant! 😂 To qualify, you need:
 
⭐Notability: Significant coverage in reliable, independent sources (think news articles, not just your own blog).
⭐Verifiability: Facts backed by published sources anyone can check.
⭐Neutral tone: No marketing fluff—Wikipedia wants encyclopedic, not salesy.
⭐Reliable references: Multiple third-party sources, not just your website.
 
We’ve got the mission, the memes, and the milestones—but fame? Working on it. Maybe if we keep growing, we’ll earn that coveted spot one day. Until then, enjoy our “future page” and celebrate #WikipediaDay with us!
