> Which is the right plugin writting way? Of course, there isn't any :) In javascript you can structure your code in almost countless ways. For a simple plugin here's what you need: http://www.learningjquery.com/2007/10/a-plugin-development-pattern but if you want to write object oriented plugins it's a bit more complicated (if you look at my profile or search on the list there are some quite long discussion about it) - though if you don't really know what is private and public just go for the link above. For a really good and short introduction to javascript I'd advise watching Douglas Crockford's videos on Yahoo Theatre. Briefly, the scope of the variable (or function) will be the function/closure it was declared in. This is the key to understand the differencies above.
$myObj.fn.extend = $myObj.extend = $.extend I haven't seen this before but it is actually a very smart thing: it reuses jquery's extend function, which will work on any object because it uses the `this` keyword, so it will be able to extend $myObj too. (see here what extend is used for: http://docs.jquery.com/Utilities/jQuery.extend). $myObj.fn is most likely a reference to $myObj.prototype but it's not indicated in your code above.
