Browser helpfulness is only perpetuating lazy author's errors. Unfortunately HTML5 has "approved" that as the right way instead of outlawing it one and for all.
(except for xhtml5)
One of the main reasons I aim for valid xhtml1 in the past and polyglot xhtml5 nowadays. The bigger reason is to have the xml toolset to automate things if/when I need them.
