Why does Stack Exchange do this? Obviously, it is tracking it, but for what purpose? Does this affect the user?

They include your id so you can earn the Announcer, Booster and Publicist badges:

as far as I know that's the only use of the user id in the link.

You get a badge for it. Who doesn't like incentives?

The three badges are Announcer (bronze), Booster (silver), and Publicist (gold).
