What else is there among legitimate sources of do-follow links?
Social media's all I can think of. It comes closer to Google's original concept of links as votes - it's just regular people sharing your site with their friends. Of course, that can be gamed, and if it can be gamed, it means there will be "false positives" down that route too. And not every site is ideal for social media.
Google has got things going in a circle - no one's linking because they're afraid to, and no one's buying links because they're afraid to... if nofollow links aren't an answer (and I love 'em because they bring actual visitors - I assumed they had no impact on ranking and never thought twice about Google when I acquired them), then there is no way under Google's rules to accomplish what Google is challenging us to accomplish. Follow the rules, and you'll have no links. Get links, and you might get penalized.
No wonder the brands are winning.
