    I think that what you said was very logical. But, consider this,
    suppose you added a little information? I ain't saying
    your content is not good., but suppose you added
    a title to maybe get folk's attention? I mean 个人介绍 - Dcr163的博客 is
    kinda vanilla. You should glance at Yahoo's home page and note how they create news headlines to grab
    people to click. You might try adding a video or a pic or two to get
    people interested about everything've written. In my opinion, it might make your posts a little bit more interesting.

    I actually do have a couple of questions for you iff you don't mind.
    Could it bbe simply me or do a few of these remarks appear
    as if thry are left by brain dead people?
    :-P And, if you are wrriting at additional sites, I'd like too keep up with anything new
    you have too post. Would you list every oone of all your
    shared pages like your titter feed, Facebook page or
    linkedin profile?
