Indeed, apologies, see my answer below.

I can make a URL which points to tiddlywiki.com and yet contains my own 
content. The ability to remotely change the content of a website in the same 
action as sharing it is pretty dangerous. For example, I could craft a link to 
tiddlywiki.com that changes the wiki so that the download button downloads 
malware. It's actually a 'cross site scripting' attack.

Best wishes
