Re-tweet depression describes the situation that you are often thrown into bouts of manic depression when you discover that your tweets/micro blog have not been re-tweeted/reposted enough. This depression often deepens when you find that your blog posts have not been re-blogged, or your Facebook status updates have not been liked.

Re-tweet depression指你的微博发布后没有太多人转发时你就会感到一阵阵的抑郁，我们称之为“微博欠转抑郁症”。如果你的博客文章没有被人转载，Facebook等社交网站上的状态也没有人点“喜欢”的话，这种抑郁情绪就会更严重。

For example:

He is experiencing re-tweet depression because no one has reposted any of his micro blog posts so far.

他正受“微博欠转抑郁症”折磨呢，因为到现在为止还没有人转发过他的微博呢。
