This is my site:

You can see it has content in closed toggles. Im thinking that to keep the page loads snappy, I should load the javascript and visibile content on the index.html. 

Then if a user clicks on the tab to expand the content, then the javascript will load the content inside the tab, and then open the tab.

Its basically just queing and limiting the amount that is downloaded initially, to try and keep it all snappy. I feel that if all the content was loaded initially (im talking about 1-2mb of information) if it seem very slow.

Is this a bad technique?
