At the bottom of each post, you’ll see something like this.
This enables you to vote on each post. You can vote it down, you can vote it up — and that’s a good thing because it lets me know what you like and what you don’t like.
If I see posts that are getting 10-15 thumbs up, it lets me know you want to see more posts on that topic or from that author. If I see posts with a lot of thumbs down, well, I assume a bunch of liberals voted that one down.
Either way, if you read a post, vote on it! I do pay attention.
