While these pages are probably older ones that are being rendered in 
"quirks mode" by the browsers that do sniffing for it, there can certainly 
be consequences to a bad comment.  Write a comment like that on a 
"standards mode" rendered page, and it'll visibly break the page in 
Mozilla/Netscape 6+/Gecko etc browsers as it tries to parse out what it 
thinks the comments' syntax is.

This usually causes comments to become visible, and actual content to 
become invisible.  It's a popular bug in Bugzilla's Tech Evangelism section 
for the way it destroys pages.
