Announcer: Shared a link to a question that was visited by 25 unique IP addresses.
How does the question page view/hit work?
Its been mentioned on both the SE blog and postcasts that the view counter on SE is conservative. So its likely your real view count is between 24 and 36 (before the meta post)
On the other hand the link tracking is defined in this answer from Jeff
There's clearly a difference between the view counter and the shared links counter and I suspect they won't release the exact algorithm for the view counter because people might try and get around it to get their question more attention by making it a hot question or to get one of the view based badges.
