The very first really interesting thought I read about this is Doc Searls’ article in the Linux Journal: The Volunteer Economy!
” … The default assumption by Wall Street and the mainstream media seems to be that Yahoo is a goner if they don’t take this deal. But in fact Yahoo is a goose that’s still laying plenty of golden eggs. And it’s laying those eggs in nests comprised of users on the Web, not on just one OS platform.
If Microsoft buys Yahoo and then insists that Yahoo develop software and services first or only for Windows, it will kill that goose. And not just because Yahoo employees will split. It will lose the users.”
