Yep, just don't vote too early and don't vote after the big guys voted ^^
And an 0.02STU upvote can change a lot for the curation.
I am using https://steemrewarding.com because it offers more options. You can even upvote paid-out posts using some simple commands, which is awesome because I like to search for some nice recipes and they are often older than 7 days and I can still give the author my upvote for it.
