Just go here, https://steemworld.org/@sunlit7

Click "delegate" on the left, then "delegate..." at the top right.

Enter the @ username and the amount you'd like to delegate, then it will ask for your "active key" to authorize.

Delegation is superior because it shows your support and because you can adjust it, or retract it at any time, so it's a little less "scammy". I also like it because it serves as a list of accounts I'm interested in. The "followed by" and "following" lists get a bit unwieldy, but the "outgoing delegations" can be tweaked at any time and lets me show support with something other than my fractional (practically meaningless) upvotes.

Also, I like how you can hover over the names and it shows their stats and how much steem-power they currently have.
