Per VanguardLH:
From a Google search on "OPML reader", 5th hit in results was
http://www.zimbio.com/OPML+Readers.
From a search on "opml" at sourceforge.net, found a project page with a
link to the project's own web site at
http://opml.sourceforge.net/.
Those are examples of what I meant by "Noise".
Zimbio has 10 listings - none of which look useful.
SourceForge just has an empty entry.
Last few years it seems like there has been a proliferation of
useless computer-generated web pages that are structured to come
up on hit lists when somebody Googles for something - but which
were not created or maintained by anybody... just the
application that generated them.
There's probably a term of art for that... but I don't know it.
OPML seems tb worse than most bc it appears to relate to RSS
feeds and some other online activities - as opposed to just
opening a local file.
So I figured I'd just cut to the chase and see if anybody had
something that actually worked for them.
