How to meet people with common interests (not dating)?

So I have a lot of interests that are different than what most people are interested in. I know that there are people out there that share those interests but I don't know how to meet them. Also I'm not trying to date them. I'm just trying to have some friends with common interests. If you have any ideas of websites or iPhone apps or something that could help me meet friends (NOT DATING) could you please tell me? I really need your help! Thanks X

Added (1). My specific interests include certain celebrities.

What are some of your interests?

What is your interest? Dancing, join a dance class.ect.

I really wouldn't recommend trying to meet people online at all - there are so many dodgy people on there!

What's wrong with the old fashioned way of joining clubs. Like sport? Join a soccer team. Like beauty/cosmetics? Enrol in a makeup course. Like helping people? Start some charity work.

If you must do it online though, I like instagram. You can search for hashtags of things you are interested in i.e. #fashion, and follow users with pictures that you like

Look for groups on facebook who share your interests.

  • Where are common places to leave an iPhone? I lost my iPhone a few days ago and have been searching my house nonstop. I'm certain it is in my house.
  • What are some iPhone free texting apps to meet new people? I really get board often so I was wonder if there were any free texting apps were you can text people who never met before. Not romanticlly but just for fun. On the is more anon and stuff. It would be even better if there was an app like that for nerdy people like Tumblr fandom lovers. If you know an app like that it would be amazing.
  • Soccer aid help? Want to meet famous people? Basically I'm going soccer aid on Sunday But the only seats I managed to get is in STH 121 really far back. All I wanted to know is if anyone knows any ways before or after the game I'll be able to see the celebrities and legends playing (particularly Van Der Sar) so I can get their autographs and pictures. Also from my seat will I get better pictures from my iPhone camera or from a normal digital camera?!
