Hi Ariel,
some things I noticed after a quick glance:
You should make the link to the demo more prominent, eg. put it on the
jquery.com plugin page. I didn't quite get what your plugin actually
does until I took a look at the demo.
About the title-fix: Whats the point of putting a links text into its
title? It doesn't provide any additional information, instead just
frustrates the user when he realizes that the title has exactly the same
content.
About noscript: I'd assume that someone with JS disabled either can't
enable it (software itself or some company policy doesn't support it) or
doesn't want to - so presenting a message "you must enable JS to use
this page" seems rather useless in most cases. I wonder if there is a
better way.
Using acronym tags doesn't seem like a good solution to the actual
problem. Usually they force me to hover the item (which is rather short
anyway) to see the "title". It would be better if the text properly
introduces the acronym and only then uses it later on.
Or it just assumes that the reader doesn't need an explanation. Putting
a acronym tag around "HTML" is a waste of time - either the reader knows
what its about anyway, or "Hyper Text Markup Language" won't tell him
anything either.
Regards
Jörn
