This is an example of "user convenience", rather than "fault tolerance".
A web browser naturally can assume http, since it will be rarer for that
user to use ftp or telnet for example.
But accepting web pages with missing tags etc. is poor practice. If all
browsers just dumped straight uninterpreted html at the point of failure
to the end of the document, more webmeisters might fix the problem.
Instead, because they "test" it with their favourite browser(s), they
"see no evil" to correct, and don't.
