Q:
OmniWeb 1.0 is picky with comments. It fetches this page, but it shows up on-screen as pure background.
This has been fixed in OmniWeb 2.0-it assumes a closed comment if there isn't a proper one.
A:
The problem with the page is that there are unterminated comments, effectively "commenting out" the rest of the page so that it is not viewable.
The author of the page should be aware that this is bad HTML.
HTML comments should take the form of:
<!-- COMMENT HERE -->
If a comment terminates with a > rather than the proper -->, it will not display. If the former were a proper terminator, then it would never be possible to comment out HTML for the purposes of debugging a page.
You might want to contact the authors of the page.
