Twitter provides a link to their javascript that reads:

src="//platform.twitter.com/...."

what does the "//" represent? I've never seen that before?

Thanks experts!

Using a URL like //platform.twitter.com will point to either http://platform.twitter.com  or https://platform.twitter.com  depending on whether or not the URL originates from a http or https URL.  This helps reduce the need for protocol detection in website code and allows developers to include scripts and API calls easier because they don't need to detect whether the site is being delivered via http or https.
