FYI: Twitter made a decision to discontinue their unauthenticated v1.0 API – meaning if you are using 3rd-party jquery.tweet.js code to embed a twitter api feed onto websites, you will notice the feed no longer works. The newly unsupported code will have to be updated to the current 1.1 version – or just run the officially-supported widget from Twitter.
Twitter wants your only option for on-page widgets to be their own Embedded Timelines. IMO, this isn’t so bad as the officially-supported widget will always be up to date and will require much less work to implement and maintain.
To install the Official Twitter Widget, sign in to your account > click the gear icon > settings > widgets > create new. Make a few selections and save changes. Embed the code provided where you would like it to display on your website. Developer documentation can be used to modify the behavior of the standard widget (width, height, number of tweets to display, etc).
