Some are just a random string of accounts; too many others recommend folks like @aplusk, @cnnbrk and @barackobama - not exactly out-of-the-box discoveries.
有的只是一些用户的随机字符串；另外太多的人用@aplusk @cnnbrk and @barackobama 这种方式来推荐用户——根本不能确定发现了什么。
I also recommend that you manually run cache: checks of all your most important pages and of various random secondary pages to get a further idea of how your site is doing on the indexation front.
我还建议您手动运行缓存：在你所有最重要的网页和各种随机检查，以获得二级页面是如何在您的网站是指数化方面做进一步的想法。
