How many answers does this question have? Write a program or a function that outputs the integer number of answers this question has. Your solution should still work as more answers are added.

Languages that run in a browser may be run from the js console while on this page. Otherwise, you'd probably have to download this page. Multi-language solutions, e.g. wgeting the page and parsing it using grep is ok. Just sum up the command line and all source used.

This is code golf; shortest answer in bytes wins.

EDIT:

Let's allow at most one occourance of the url of this page to not count, either as input or in the source. No url shorteners, no data stored as get parameters etc. Quotes around url, if needed, still count. Taking the url as input is also fine. If you want to remove some part of the url, e.g. /how-many-answers..., you can, but it probably doesn't help you.
