Twitter is a great resource for sharing – be it blog posts, news items, images or videos. But what if you want to share more than that? Twi.tt has you covered. Twi.tt lets you share pictures, video, documents, audio and even polls on Twitter. Using your existing Twitter account, simply fill out the simple form on Twi.tt’s home page, add your own intro text and hit send. Images and video can be uploaded, shared from URL or captured via webcam. Upload or share documents by URL. Polls are created onsite, within the dialogue box that opens when you select the polls option. The result is a link posted in your Twitter stream that leads back to the poll box. While music sharing is not yet activated, it apparently is on its way, as there is an audio sharing button on the home page. In the meantime, there are plenty of other music sharing services that link to Twitter to hold you over until Twi.tt finishes building its site.  A simple tool with a simple, but very useful purpose!
