Twitter Updates-OAuth for all applications & t.co as Official Link shortener

Twitter announced two new updates on August 31, 2010

Email as sent by twitter:

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.
Desktop and mobile applications may still ask for your password once, but after that request, they are required to use OAuth in order to access your timeline or allow you to tweet.
What does this mean for me?

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, and we then will forward you on to the destination URL. All of that should happen in an instant.

You will start seeing these links on certain accounts that have opted-in to the service; we expect to roll this out to all users by the end of the year. When this happens, all links shared on Twitter.com or third-party apps will be wrapped with a t.co URL.

What does this mean for me?

A really long link such as http://www.amazon.com/Delivering-Happiness-Profits-Passion-Purpose/dp/0446563048 might be wrapped as http://t.co/DRo0trj for display on SMS, but it could be displayed to web or application users as amazon.com/Delivering- or as the whole URL or page title.
You will start seeing links in a way that removes the obscurity of shortened links and lets you know where each link will take you.
When you click on these links from Twitter.com or a Twitter application, Twitter will log that click. We hope to use this data to provide better and more relevant content to you over time.

Update: Twitter Changed Its Terms Of Service

mm_twitterTwitter has updated its terms of service. Please read them before using Twitter as there are many changes.

Here is the abstract from Twitter’s Blog:

Now that we know more about how Twitter is being used, we’ve made changes to our Terms of Service—these are the basic rules that go along with using Twitter. The revisions more appropriately reflect the nature of Twitter and convey key issues such as ownership. For example, your tweets belong to you, not to Twitter. With these revisions, we expect some discussion so here are a few highlights from the updated page.

Advertising—In the Terms, we leave the door open for advertising. We’d like to keep our options open as we’ve said before

Ownership—Twitter is allowed to “use, copy, reproduce, process, adapt, modify, publish, transmit, display and distribute” your tweets because that’s what we do. However, they are your tweets and they belong to you.

APIs—The apps that have grown around the Twitter platform are flourishing and adding value to the ecosystem. You authorize us to make content available via our APIs. We’re also working onguidelines for use of the API.

SPAM—Abusive behavior and spam is also outlined in these terms according to the rules we’ve been operating under for some time.These updates complement the spirit of Twitter. If we’ve left something out, or the nature of the service changes, then we’ll revisit the Terms—there’s a feedback link on the page
