  1. Hi exceptional blog! Does running a blog such as this require a great deal
    of work? I have very little knowledge of
    programming however I had been hoping to start my own blog in the near future.
    Anyway, should you have any recommendations or techniques for
    new blog owners please share. I understand this is off topic
    nevertheless I simply had to ask. Thanks a lot!
