According to all my experience till now, The Easiest way to increase my Buzz points (Weather you believe or not) 
It is to buzz others 
In simple words just open profile of any person,
Check all his/her uploads and make buzz at each n every post.
As a result you will definitely find an increased Buzz Rank.

Don't believe?

Just do it.
