Here Comes Everybody: The Power of Organizing Without Organizations

I'm completely absorbed by this book. If you're interested in how the Internet and social media in particular have changed and are continuing to change people's participation in groups and in society, you should read it!

It's interesting to notice that the word people is plural, so we say, "people like hot dogs." But everybody and nobody are singular and we say, "everybody knows that pigs can't fly", or "nobody still believes in Santa Claus." The same thing is true with somebody, as in "somebody keeps stealing my chair."

We use anybody for questions, like "does anybody know where the cookies are?" And also for negative sentences, like "I didn't know anybody at the conference." A different kind of negative sentence has nobody as the subject, and then the verb is positive, as in "nobody answered my email."

We use somebody when we know that a person did or said something, but we don't know who it was, or we don't want to say who it was.

P.S. I've added a link to Amazon. If you've never ordered books from them, I highly recommend trying it. For one thing, books coming from the U.S. are really inexpensive, especially with the high euro. Also, Amazon was an internet pioneer and a number of things we take for granted came from them.
