Hi again,
Really good questions :) and thank you.

1. First of all I noticed this morning that when I am in the beginnin of the day my first vote is more valuable than the others which posts voted by me but later than the first one.
2. After I learned or noticed that I thought it was a good point because it makes more valuable your first votes and it makes sence for blocking spam votes and I have to think more than before cuz I have to be sure has it enough quality to render?
3. After I realized I becamed more carefull about my votes and voters :) I share it with my friend.

I am at the beginnig, I have to learn more..
