Would you capitalize the word facebook if are writing about it?

You should capitalize "Facebook" when referring to the company or its platform.

Here's why:

* Proper Noun: "Facebook" is a proper noun, referring to a specific entity (the company and its social media platform).

* Brand Name: It's a brand name and is therefore capitalized.

Example:

"I posted a picture on Facebook."

However, you wouldn't capitalize "facebook" if you were using it as a generic term for social media, like:

"I spend too much time on facebook."
