A new mobile version of Twitter has been announced that'll use less data and work better on 3G/2G networks. Twitter Lite isn't a new app, but rather a lighter version of the network's mobile site. With its Data Saver mode, the site should be more accessible to a wider range of people.
Data Saver reduces the preview quality of videos and photos, and you must click the preview to gain access to a higher quality version.
Twitter Lite also comes with offline support.
The updated site has been designed with "emerging markets" in mind. It's rolling out globally.
Today, we are rolling out Twitter Lite, a new mobile web experience which minimizes data usage, loads quickly on slower connections, is resilient on unreliable mobile networks, and takes up less than 1MB on your device. We also optimized it for speed, with up to 30 percent faster launch times as well as quicker navigation throughout Twitter. Twitter Lite provides the key features of Twitter -- your timeline, Tweets, Direct Messages, trends, profiles, media uploads, notifications, and more. With Twitter Lite, we are making Twitter more accessible to millions of people -- all you need is a smartphone or tablet with a browser. - Twitter
