there will always be people around who share your hobbies/interests. fb is a good source of online socialising if that meets your needs. there seems to be group pages on just about anything plus websites etc. opportunities all of kinds can present themselves at any time and they can lead to positive things sometimes. even something as random as overhearing a conversation on a subject that you have an interest in.
i know it can be boring but there is nothing wrong with going against the grain. its more fun sometimes
