I like http://www.visualjquery.com for my jquery documentation...
yes there is lots of room for "improvements" but it's a working and living project which is constantly changing and I think the project managers are doing a great job to date... and demos? look at the plugin pages for demos... imho the core documentation should only be techinical with little to no examples... like the link above, they give a two liner example with before and after expectations.... that is more then a programmer deserves and is just icing on the cake... asking for demos of the core is like asking the creators for included libraries in any language (like c, c++, etc) to provide demos of the library functions when the coder only needs to know the name, input parameters and the expected output... ~Terry
