【web】why people here read a lot ,communicate little

　　　　I just cut a picture from homepage ,i am wondering ,why there are hundreds of people have read the article ,but usually  less than 5 pieces of comment, the most  is 0. but think about myself ,i don't comment at usual ,but i will do more ,at least press the recommend button .i think it's a good way to encourage the writer .But i don't like people comment in my blogs ,i just write something for myself ,just like diary .
