Contribute to Your Communities. Just like in the physical world, giving back to your community is a surefire way to make sure that the places you spend time are great places—and that they remain that way. Comment on the articles on your favorite blogs, forums, or communities. Engage them. Agreement is always nice and certainly welcome, but constructive and respectful feedback when you disagree is even better. After all, no one gets better when everyone agrees with them, and no one wants to get better when they’re surrounded by trolls. Better still is when you bring you own ideas to the table as part of a bigger, broader discussion. We’ll get into this a bit more later, but actually participating with your own opinions, alternatives, and perspectives—even when you agree—is the hallmark of a good internet citizen.

We’ve mentioned how important it is to get involved and contribute, but your contributions will go farther if you’re familiar with the community you want to join first. Get to know their rules; in some cases, it can help to lurk long enough to learn the in-group language and informal dos and don’ts. Remember, you’re likely contributing in a private place, so before you complain that you’re being "censored" or your "freedom of speech" has been violated, remember which of your rights apply where (namely, that the First Amendment only protects public speech, and comments on a blog or Facebook posts are anything but, even if most sites try to offer their users that same freedom. The more you learn, the more likely it’ll be that you’ll be able to contribute positively when you do start talking.
