This is a brilliant move by Marissa Mayer. She knows from experience that having the best of the best (not only in engineering- but also in design, marketing, etc.) is necessary for your success in tech. Large tech companies depend on their employee's pet ideas and projects, the fact that they might be well known in some niche for some open source project or blog, and so on. In a way, if you're a large company that needs to constantly be on top of the latest trends and technologies (because if you're not, the same thing happens to you as happened to Myspace), you're no different than YCombinator - except that instead of wanting your recruits to start their startup, you want them to run a project for you internally (all of the famous Google projects that originated from 20% projects could have easily been startups of their own).<p>Through these actions and posts, shes's showing how cool and fun Yahoo! is. Look, the CEO works on weekends with a small skunkworks team on designing logos, and nerds out on the subtle details like any cool designer would do.<p>This is all about making Yahoo! a desirable place to work at again. I'm receiving way more emails from Yahoo! recruiters these days than Google or Apple recruiters, and they all have a common tone: "check us out, we're fun!".<p>Similarly, all the small startup acquisitions have 2 goals: poach for talent, and get Techcrunch, HN, Engadget, etc. to talk about Yahoo. (the big acquisition we all talked about was about receiving a mature project internally as a way to make up for lost time)<p>Of course it's not just this that will bring Yahoo! to victory, but those little things show how much strategy there is in Mayer's execution.<p>EDIT: finally was in a situation where I could watch the video, and I only feel stronger about my point. Listen to the music (some dubstep/ibiza dance/feel good summer hit hybrid) - this is clearly destined to appeal to the 21 year old Stanford student looking for a new job, not the guy on HN who will criticize anything that makes it to the front page.
