Today is NOT the day of the Carnival of Creative Writing, which has instead been pushed back to May 11. Please make a note of it. Theme is "renewal." No crocii.
Today is also not the National Day of Truthtelling [about sexual violence], which was on Saturday, but you can still read about it at Ubuntu.
