I don't think you understand how it works. Visit one of the hosts and login. It uses steemconnect and it is to verify you have a proper steemid. Once you are confirmed, there are banner ads on the pages which pay based on views or clicks. If you hover your computer mouse over the ad you can what it is worth. Some are worth 0 while others are worth 1 steem. Once the summation of all of your rewards reaches 1 steem, you receive 1 steem power delegation which is updated daily.
The current value of the delegations can be found at https://steemworld.org/@steemhost01
Just visiting the various hosts on a daily basis does two things. It increases your chance of increasing your steem power delegation (and the hosts as well). Over time this will mean that you own posts on steem and the curations you do will increase in value. It also introduces you to a new set of steemians whose content might be of interest.
