The central paragraph of this is still really hard to parse:

"At its core, OAuth for delegation is a standard way to do the following:

The first half exists to send, with consent, a multi-use secret to a known delegate.

The other half of OAuth details how the delegate can use that secret to make subsequent requests on behalf of the person that gave the consent"

This paragraph has a bunch of words that need defining (the word delegate does not appear on the page until then) and a confusing use of 'first half', 'second half' .... First half of what?

Surely it can be explained better than that?
