You most closely resemble a Maven!
Mavens are specialists within a particular field. They love to collect information and pass on their knowledge to others just because of sheer will. You are likely the person to tell a few people about a particular restaurant or hotel you feel strongly about, and maybe you can even get a few of those people to take your advice. A maven is someone who doesn't want to necessarily persuade you, rather educate and help you. Having a loyal group of people that trust in your opinion is critical in starting word of mouth epidemics.
