Twitter’s recent announcement of expanded tweets may change that. You’ll be able to preview the headline, intro and videos and photos without clicking through. If the preview is enough to warrant a re-tweet or favorite, you can do that from the expanded tweet, too.
As more journalists scan for news from smartphones and tablets, previewing will be a welcome time and bandwidth saver. Expanded tweets are already available on Twitter.com, and Twitter’s mobile site and are expected to be available soon on Twitter’s mobile apps for iPhone and Android.
