Todays internet search engines are perfect for locating and then interacting with people with the same interests and hobbies as yourself. In the past people had problems where there were no local clubs if their hobby was not a hugely popular one, so many people missed out joining in with others who enjoyed their hobby. Today though virtually every conceivable sport or passtime has its own network or sites and forums. Be careful making friends with unknown people online though, remember that some people join such communites with malicious intent, often they want to sell something to the other members. Look into who a person really is, try google to search for info, or use a reverse lookup tool.
