Okay, I have a bone to pick with the Pottermore website, both old and new.
Where the hell is Tom Riddle? Where is Lord Voldemort? Even when JK came out with that comprehensive timeline on Wizarding history’s most famous witches and wizards, Voldemort was not on there. Grindelwald was. Some of the older Dark Lords were. No Voldemort though. No Tom Riddle. Even the Slytherin House page has no indication that Tom ever existed, and for someone who is widely considered to be the most dangerous Dark Lord of all time (I believe this was in the books if I remember correctly), you would think there would be some indication that he was there.
It doesn’t matter if you love or hate his character, he was one of the biggest players in the series and to see him be completely neglected is awful. I don’t know if JK has a book about him or something in the works or she’s just being biased, but even Harry got more backstory, and he’s the main character. We lived in his head for 7 years. We only got a glimpse of Voldemort’s life in Half Blood Prince and barely a tease in Chamber of Secrets, and it’s almost sloppy to go through all that time making him out to be a mortal just to ignore him on the official website.
