Your votes won't have a huge effect so you may as well use it as you like. Nobody is really missing out if they don't get it. What you can contribute are your comments. Some of us are really into the conversation.
My vote is not huge, but I use it to support the content I think needs more exposure. I also re-steem to my followers, but I don't always see that make much difference. The fact is that Steemit is pretty small. You may not get a lot of random visitors, so you have to get out there.
Thanks for the advice and support on my posture. I will resist external pressures and only vote on content I feel needs to be seen by others.
