I have seen that many question get a bunch of upvotes after a start,there are many questions which remain unnoticed for several time and once it get some upvotes its popularity start increasing. Doesn't that indicate that most of the people upvote a question because it is upvoted by others. Shouldn't this thing be stopped,that is the reason some exellent questions remain unnoticed. Hope my message reach to those who are responsible for this. thanks.
