Christian Heilmann compares the Object Literal to Douglas Crockford's Module pattern and finds that the Module pattern fixes a major problem of the object literal - the difficult choice of using this or fully qualified references to functions in the same block. Christian also covers the improvements in the Module Pattern, like the decluttering of the return block, which makes the resulting a little easier to work with.
Christian Heilmann offers us Dishy, a JavaScript REST API for talking to del.icio.us. Taking full advantage of del.icio.us' JSON format and the script element, Dishy doesn't need a server-side proxy. Its a useful helper class for easily getting information from del.icio.us.
