Link Manager的作者是WordPress,目前有60,000+个有效安装。已经Tested with 3.5.2版本的wordpress。
In WordPress 3.5, the Link Manager (which some use to build blogrolls) will
be disabled by default. If you have links when you update, it’ll still be there.
But you can use this plugin to ensure it will always be there, even if you
update to a later version of WordPress or remove all of your current links.
