After read the post from @cryptokannon I made this post to fulfill my achievement6 for the newcomers community, on the following questions:

Do you understand how voting and curation work in steemit?

Voting is the act of engaging a post with a gesture just as the like button on social media, but in this sense it can be adjusted in form of rating you are willing to give to the post. The voting button can be adjusted between 0-100 and this serve as a reward for make good content on the steemit platform. The voting come in a value according to the number of steem power held by the voting account.

After voting a post, the post will be. Able to pay out steempower, sbd and steem after 7 day from the making of the post. Of which on a post with above 0.02 can be able to pay out. 50% of the post pay out goes to the author of the post while the other 50% goes to the voter of the lost known as the curator.

Curation is the act of voting a post and the curator will get 50% of the reward given to the author in proportion of the given vote. The voting power of each account reduce in accordance to the volume of upvote given at a go and this is measured and displayed by the voting mana. This can be viewed by use dapp like steemscan, steemnow e.t.c.

What happened if you vote a post before 5 minutes marks after posting?

When a post isnbeen made and upvote is given to the post within the first 5 minutes of making the post, the curator reward are as follows;

Time	curator reward	reward pool
2-20 seconds	0 %	100%
≥1 minute	20%	80%
≥2 minutes	40%	60%
≥3 minutes	60%	40%
≥4 minutes	80%	20%
5 minutes and after	100%	0%

Who will you vote for Steem Witness ? and Why?

Steem witnesses help to validate transaction on the blockchain and they uses delegated proof of stake as the consensus mechanism. I voted for @steemchiller because he is No1 showing he is best for what he does and also been impacting the platform. @justyy too because of the work done on @Steemyy.com a great dapp project I reviewed on my achievements5 task 3.
