Those who participate of Internet News Groups don't know how many people read their messages or posts, and do not have a clue of the other participant's opinion. In all, there are many phenomena of integration in a news group to be considered. Most people only read and do not answer them. Most of the time people only answer when the subject of interests to them, and when they have a completely different opinion, or when they agree and want to complete the thought that was presented. Lastly, we have to consider that people end up getting to know each other in the same group.
Participants often tend to be the same ones and everyone knows their opinions.
Many times there is a difference of opinion about a certain topic, but the participant does not want to go through the hassle of responding to one or more persons. My suggestion is very simple and can be organized in a site specialized in news groups. Firstly, there would be a count of how many times a specific post was read. In the newsreader, there would be an opportunity to vote by clicking on icons in reference to each message, without necessarily having to answer in writing. When we looked at the news list there would be the possibility of being informed about the number of times a message was read and the opinion of whom read it.
