Why is it considered weird if someone has less than 1000 Facebook friends?

Four digits is probably in the extreme high range.

If someone used the site roughly since it's become public, adds a significant fraction of their acquaintances, and doesn't "un-friend" people on a regular basis, they're likely to have accumulated a three-digit number of contacts.

It is interesting how many people think of what amounts to an online local phonebook as a measure of social success of some sort, though - as if they can't quantify how charismatic or likable a person is just by talking with them. Of course, getting angry at people with "too many" friends shows that someone cares a little too much about their number just as well as someone who adds people they don't really know
