Sure, but this is why pretty much every resource on Tor stresses the importance of end-to-end encryption for sensitive or identifying info.
Those that support HTTPS: news.ycombinator.com; twitter.com; www.torproject.org
Those that don't: cryptome.org (!); zzaper.co.uk (the Vim tips article from a few days ago); forbes.com; vimeo.com; nytimes.com
End-to-end encryption would be great, but the internet at large just isn't there yet in terms of both HTTPS support on most sites and safeguards against SSL tampering.
