When you click on these links from Twitter.com or a Twitter application, Twitter will log that click.

Aha. Und wie es aussieht, wird es schwer sein, diesem “Service”, von dem Twitter auch schreibt: “We hope to use this data to provide better and more relevant content to you over time”, zu entkommen. Eine schöne Formulierung: “we hope to use this data…”

Es wird auch interessant sein zu sehen, was das für Dienste wie Bit.ly und Ow.ly bedeutet.

Hi @spielkamp,

Over the coming weeks, we will be making two important updates that will impact how you interact with Twitter applications. We are sending this notice to all Twitter users to make sure you are aware of these changes.

What are applications?

There are over 250,000 applications built using the Twitter API. To use most applications, you first authorize the application to access your Twitter account, after which you can use it to read and post Tweets, discover new users and more. Applications come in many varieties, including desktop applications like TweetDeck, Seesmic, or EchoFon, websites such as TweetMeme, fflick, or Topsy, or mobile applications such as Twitter for iPhone, Twitter for Blackberry, or Foursquare.

Update 1: New authorization rules for applications

Starting August 31, all applications will be required to use “OAuth” to access your Twitter account.

What’s OAuth?

OAuth is a technology that enables applications to access Twitter on your behalf with your approval without asking you directly for your password.

Applications are no longer allowed to store your password. If you change your password, the applications will continue to work. Some applications you have been using may require you to reauthorize them or may stop functioning at the time of this change. All applications you have authorized will be listed at http://twitter.com/settings/connections. You can revoke access to any application at any time from the list.

Update 2: t.co URL wrapping

In the coming weeks, we will be expanding the roll-out of our link wrapping service t.co, which wraps links in Tweets with a new, simplified link. Wrapped links are displayed in a way that is easier to read, with the actual domain and part of the URL showing, so that you know what you are clicking on. When you click on a wrapped link, your request will pass through the Twitter service to check if the destination site is known to contain malware,……
