Tweet.io
Interesting combination of utility with communications/broadcast, there are about 4 things this could disrupt if it works:
*Just use a Drop.io input to get it in your drop!
* Have something to say? Call it in
* Take a mobile photo? MMS it in
* Want to share a link? Click your bookmarklet
* Finish a podcast? Upload it to your drop
* Share a video or song? Embed or Upload it
* Share some office documents? Email them in
* Distribute files among your team? Setup a dropbox widget
* Need to share some hard copies? Fax it in
..as these inputs are received, Drop.io will immediately share these assets with your entire Twitter stream with a convenient link, while saving all of these assets in a single drop - in fact, you can think of Drop.io as your ultimate Twitter asset archive.
