i've banked with monzo since 2019. it's exactly what britain should be producing. built from nothing, forced every legacy bank to modernise, and now one of the biggest consumer banks in the country and we're about to sell it to brazil investors deserve a payout, fair enough. but the reason it's a sale and not an ipo is that our ipo market is dead. so our best companies get bought instead of listed deepmind to google. arm to softbank. our car makers, our steel, our water, our airlines. now monzo we build them and sell them. every. single. time.
EXCLUSIVE: Monzo, the digital lender which has become one of Britain's biggest consumer banks, is in talks about a sale to Brazil's Nu Holdings which could value it at between ยฃ8bn and ยฃ10bn, ending the prospect of a near-term IPO of a UK fintech champion. news.sky.com/story/digital-bโ€ฆ

Our statement on the UK governmentโ€™s demand that all content on all devices sold or used in the country be scanned, on the presumption of nudity, using a dystopian combination of age verification and content scanning. This proposal will not safeguard children. It endangers us all. signal.org/blog/pdfs/2026-06โ€ฆ

skill issue
This book must be the sole reason millions of people were permanently turned away from the field because of how ridiculously dry it is. Couldnโ€™t get through half a page without passing out in a concussion coma. Almost convinced me to change careers. Beginners: avoid this.
