I think this is the best answer so far, if the things you used to love don't satisfy you the way they did, you're probably burnt out. If, on the other hand, your not meeting your own expectations stems from screwing up priorities (avoiding what you don't enjoy), you're likely just being lazy.
If I spend too long on a project that I just want to finish, I generally find myself looking at other more interesting projects and working a little on them.
Sometimes this is being lazy but sometimes you just need the change to get back on track with your mundane project.
Who is this Hitler to tell other people how to use Twitter? If you don't like it - don't follow it...YOU are taking the decision to follow what I write....eat it or don't..
Presumably on the google website the script is loaded via an xmlhttp request which then strips the initial text and evals the rest. By added the initial throw 1; they prevent other sites from including the script, since it won't do anything.
That's extremely smart. XMLHttpRequest protects you via the same origin policy. But there are other ways (such as JSONP) to load JavaScript and bypass the same origin policy. It's not like you cannot opt out of things like JSONP, but this trick adds another layer of protection and is particularly useful in fighting XSSI.
If another site would really want to include the script, it could also strip the initial text. Is the purpose only to avoid people from including the script by mistake?
