2026
- March 1, 2026: Now it's time for the 44,000th article. We have only 1,000 articles left before the small 45,000th article milestone. But the integer article creation blowout's timing is actually unsustainable.
- February 18, 2026: This is the 43,000th article approach. We are nearing the 45,000th article milestone soon during the brief integer article blowout.
- February 14, 2026: Happy Valentines Day, we have now reached the 42,000th article. 3 days after the previous milestone from the integer-related article creation blowout! Here we go!
- February 11, 2026: We reached the 41,000th article. What the hell is the natural number article creation blowout!?!
- January 31, 2026: We celebrated a major milestone with the 40,000th article! But this major milestone is a fair bit smaller than the 30,000th article one. The article creation blowout is back again!
