Fetch Tweets from Twitter
This is a WordPress plugin that allows you to fetch tweets from twitter.com and display them anywhere you want such as in the sidebar, posts, and pages. Not only you can show your tweets to your visitors but also mash up multiple users’ timelines and display the combined results.
It is developer friendly and support additional add-ons and themes to be written by other developers. One of the extensions supports feeds so you can subscribe your favorite person’s tweets as RSS, which has become harder as the Twitter API was upgraded and the previous version no longer support tweet feed without authentication keys.
If you are a programmer, you can import the tweet data as JSON to your application by making the WordPress as the own Twitter API server with that extension. It’s called Feeder.
If you are a theme developer, you can easily customize the template for the tweet outputs. Just copy the existing template and modify the copied files and rename the template name. And there you go. Your own template will be listed in the plugin’s setting page. This way, when the plugin updates, you won’t loose your modifications.
