Welcome to the Q&A Forum

Fascinating.  If it works and suites your needs that is what matters.

I'm pretty sure that's what's happening. So mendely.com is a book mark approach to tabs, as opposed to the javascript ? variable and then bookmark approach here: http://ugmo.com/?quicktabs_1=1#quicktabs-1 I can see how the content is all on the page. Is there any dilution with the bookmark approach? To what extent is http://www.mendeley.com/#mobile different than http://www.mendeley.com/ ?
