The world of Twitter is a subject I have written about several times in this newsletter and in my Network World Gearhead column. The reason for this mini-obsession of mine is that despite all of the service problems and outages that Twitter has experienced over the last few months it remains one of the most addictive social media ever created. Moreover as Twitter also offers a completely functional API that allows third parties to create clients and mashup services that extend and enhance the Twitterverse it has continued to grow in importance as a keystone of social networking.

Today I have another clever service in the Twitterverse for you: TweetCube published by Anything Cashable.

The purpose of Tweetcube is to support file transfers via Twitter. The service is free and no registration is required - you simply enter your Twitter ID and password in the form on the TweetCube home page and then specify a file to upload (currently limited to 10MB and purged after 30 days), and an associated message.

TweetCube stores the file on its server and creates a Tweet (the name for a Twitter message) containing the message you entered and a short URL for the file. Anyone clicking on the URL in the Tweet can retrieve the file.

If you want to attach a previously uploaded file to another tweet TweetCube remembers your uploads. You can then choose from your list of files currently stored on TweetCube, but with one problem - TweetCube forgets the original file names and assigns a cryptic system name to each file.

TweetCube remembers you using cookies and should your cookie get deleted you simply have to re-authenticate using your Twitter credentials for your previously transferred files to be available to you again.

While the service is (unusually) not labeled as being in beta the service is definitely a work in progress and TweetCube pays the bills through site advertising and sponsorship.

It’s a nice, tidy service that works well and is worth adding to your armory of social networking techniques.
