They log every single pageview to SQL Server. There are plenty of writes to various other counters, recommendation system, message inboxes, analytics, etc. Also the ads system, although I'm not sure how much of that is still 3rd-party.
Yes it's read-heavy but there's still plenty of work done in assembling a page. It's definitely not as simple as caching at the CDN edge for every hit.
