Twitter just followed the step of Gmail to set the option to let the users visit it by https connection.

If you always visit Twitter under a open and shared network such as unsecured WiFi connections,you’d better to opt it to ensure that your information will not be hijacked easily.

Some Twitter clients have been providing the service via https,however that’s not all.I hope they could improve it as faster as they can because quite a number of people login into Twitter though the clients in public area by WiFi.If you always login to Twitter by mobile browsers,make sure you key in https instead of http.

Have a secured surfing!
