Twixxer.com is a new service that allows Twitter users to move beyond the normal text-only constraints of sending Twitter updates.
Instead of simply providing a text link to the digital media you’d like to share, you can use Twixxer to send a photo thumbnail or a video player directly to your buddies’ Twitter pages. The service is comprised of a browser add-on (Firefox only) and a web service, and uses the Greasemonkey extension. Users upload photos, which Twixxer hosts for free, and the program generates a short URL to include in your tweet. The URL links to the original version of your photo or video, and will appear as such for anyone not using Twixxer. But anyone with the tool installed will instead see a thumbnail photo or video player under the update when they visit Twitter.com. Non-Twixxer users will find an easy download link for Twixxer when they click the URL to see your photo or video, so they can jump in on it too. Currently, only Viddler and YouTube videos are supported.
Twixxer.com In Their Own Words
“Twixxer is a photo and video sharing component for Twitter.com users who are normally restricted to text-only updates that contain links to media. It is comprised of a browser add-on and a web service.”
Why Twixxer.com It Might Be A Killer
Adding photo and video sharing to Twitter’s current capabilities is a huge step up from text-only, and users will surely appreciate being able to view the video or photo from their current page instead of navigating away or opening a new window to view the media content shared in their friend’s tweet.
