What is the Pizza Without Cheese Problem? When a low-effort input produces an unimpressive output that nobody wants, the product gets the blame. This might be why your users aren't experience Aha! Moments. New Cheatsheet dropped today for BFM+ subs. builtformars.com/cheatsheets…

I paid a bot farm to boost my Twitch profile. I ran ads, I made some money. 💸 builtformars.com/case-studie… • What is the experience of being a Twitch streamer like? • What happens when you make money? • Why, oh why, are they telling me to redeem my 'BigBoyUndies'?

small workflow update: I’ve added @builtformars to this flow via MCP, and it fits really well! bringing strong UX patterns and product references into exploration before ideas move forward.

Designers at big orgs drown in solution-first thinking, context-switching, and firefighting. With the new @builtformars + @mobbin MCPs, I can finally challenge shallow ideas with real data at hyperspeed. This positions us designers as allies.

Built for Mars (@builtformars) is smart as fuck. They built over YEARS a solid bank of smart UX examples. Now they've built an MCP for your agents to find the best UX for your app. It's genius and a hint at what every service provider should do. docs.builtformars.com/overvi…

Such a useful platform. It has design case studies from docusign, apple, nike, monzo and @PeteRamsey has categorized it by industries and ux objectives

So I boot up Duolingo, ready to lose another game of chess. ♟️ "𝘞𝘩𝘢𝘵? 𝘙𝘦𝘨𝘶𝘭𝘢𝘳 𝘢𝘱𝘱𝘴 𝘤𝘢𝘯 𝘶𝘴𝘦 𝘪𝘖𝘚' 𝘚𝘤𝘳𝘦𝘦𝘯 𝘛𝘪𝘮𝘦 𝘵𝘰 𝘣𝘭𝘰𝘤𝘬 𝘰𝘵𝘩𝘦𝘳 𝘢𝘱𝘱𝘴?" I wonder if Starbucks would ever offer free drinks to users who agree to block access to other coffee loyalty apps during their morning commute.
