Some families have a messenger that help convey and respond to message from other family.(API Calls).

Now let's say the Head of Family A refuse to oblige request of other family due to some internal crisis, no information can get through to the members of family A. When Family finally resolve the internal crisis, they miss out on some tangible information. This is how Web2 works. You can visualize some other scenarios which can prevent this setting from scaling. that is what web3 is solving.
