I am seeing this more and more every time, its not what Steemit is about OR maybe you don't know about it.
You come to Steemit to:
Write your own posts,
Read other members posts
Comment on that post.
Vote on other members posts.
When you do this those members will usually come and return the favour.
If you don't follow these then members are going to ignore your posts, you are supposed to vote, that's how Steemit works. Oh and we can check if you have voted, we know when you have just commented. This isn't good.
Pressing the vote button couldn't be easier, really it only takes a second, it then gives the poster a little bit of earnings.
If you need extra help, this is what you are looking for. The green arrow, once click and your done.
Thank you @son-of-satire
