You can join communities with people who have the same interests as you.
This includes fan sites such as this one where you can participate in the fandom by editing pages and creating your own content.
Maybe you can even find true love?
Not all these groups exist just for fun. They are, however, just as useful.
Some of these communities exist just to provide emotional support.
Some communities are there to provide you with useful advice.
Sometimes there are not-so-helpful answers.
Some communities may have an obvious and direct impact offline.
It can even be powerful enough to support political movements.
Or Occupy Wall Street
Some online communities are changing their ways to become more inclusive.
But at the end of the day, not all communities are happy places.
So try not to let things you see online ruin your day because others are being rude.
