Improve responsiveness of Twitter feed on News page

[kintopp]

The Twitter feed takes quite a bit of time to load and render. Long enough that an impatient person might think the page isn't working. Can we add something like 'Page Loading..' placeholder before div with Twitter's widget.js loads? Or some way to pre-fetch, cache, and then render the cached content?
