About Me
I've always loved the feeling of opening the mailbox and finding the latest issue of a magazine you've subscribed to for years. Growing up, my favorites were ESPN The Magazine and Architectural Digest. These days, we're constantly sharing videos, photos, and opinions - so why not our own magazines? Qorrum is a platform where anyone can create and share their own monthly magazine, and explore ones made by others. Mine will usually center on cumulative knowledge, major tech developments, and general learnings - though each issue will take a slightly different shape!

Miscellaneous September 2025
“It seems a common experience in the lives of people with high agency is that they, at some point, metaphorically, lean against a wall and discover that there is a hidden door. they get into the habit of testing if walls are actually doors, and the more they do so, the more examples of hidden doors they find, and the more inclined they are to look for them.” (Henrik Karlsson)

America’s Phenomenal Geography
Jamie Dimon once said: “America has the best hand ever dealt of any country on this planet today ever, okay. And Americans don’t fully appreciate what I’m about to say. We have peaceful, wonderful neighbors in Canada and Mexico. We’ve got the biggest military barriers ever built, called the Atlantic and the Pacific. We have all the food, water and energy we will ever need.”
Michael Gridley posted a great Twitter thread expanding on the tremendous geographic hand the US has been dealt a few takeaways below:
