From my personal experience it has more impact than one would think. Remember there are many new investors who sometimes believe anything they read and get spooked at the slightest of things. I got in this stock as a matter of fact when a poster was spreading rumors all over ihub that were not true. It allowed me to get in at the 1-2 cents range when many people were selling from fear since they believed this poster. Always remember the saying buy on fear sell on strength or greed as some like to call it. GL!
