The value of the steem fluctuates. Since you are new, your vote is sometimes worth less than a cent. (I was very excited when I could finally literally put my two cents in!). So as long as it's turns blue, you've upvoted. Also you can "resteem" my stuff. It's like sharing on Facebook. It gives people another chance to see my post in the news feed, if just for a moment before it's washed away in the deluge of other posts. Re steem is the square arrow in the bottom right hand corner of the post (to the left of reply). Glad you're here. Start posting about the trials and tribulations, successes of threadfarm.
