It is seriously unnerving reading posts that use that many exclamation marks! Exclamation marks should be used sparingly, to preserve their power to deliver impact! Someone who uses exclams for every sentence comes off as either loud, vapid, or just super-caffeinated! In fact, a good rule of thumb I've heard is that one out of every one hundred sentences deserves an exclam!
In Japanese writing and I think older styles of English writing as well ('older' as in Victorian/Edwardian, not as in Elizabethan/Jacobean/Caroline/Restoration/Georgian) overuse of exclamation marks is considered characteristic of an ultrafeminine style, and for that reason I'm skeptical of using the word 'vapid' to describe it, but other than that I had the same reaction to that post.
