I'm not "lauding", I stated that it appears like the move that both sides want to make. A small company gets to take the lead on mobile where they can potentially make a very big difference, much bigger than they could make with their existing company, and really a rare opportunity that not many people get. Mayer gets good talent that she trusts to help lead an important part of her organization. If it works out like they all plan, then it makes those Yahoo! shareholders who subsidized that acquihire very happy.
If you've used the product, you can see that it was beautiful, usable, and the performance was solid. If we assume that the product is failing (even though they've raised two rounds of funding from seasoned and celebrity investors alike), we know that the team can execute well. Mayer wants to move to mobile-first, so acqui-hiring a team who know how to build well for mobile can be a smart move. It may also attract talent who respects that team. Perhaps Stamped wasn't growing like they planned, but I'm sure they and Mayer think that with the right direction at Yahoo they can do great things.
Who knows if it will work out. But it seems like a solid partnership for both sides.
Either way, they aren't my target market. My target market is the overlap of those who care and can afford to pay what I require. Outside of that, companies can do what they feel best for them.
* Annoying because it does promote cheap+fast design, which doesn't usually provide the desired results, and these companies may possibly devalue design even more.
