Pigeon Carrier
Due to the increasing proliferation of Twitter as a mass-messaging system and a replacement for short emails, Karthik Viswanathan and I decided to make Twitter more useful by adding in attachment functionality.
In the status quo it is already possible to add pictures and videos to tweets; however, the methods to do so require individual signups and do not allow management of uploaded files. Moreover, when adding multiple files, the number of corresponding links increases, decreasing the number of characters remaining for the actual tweet.
Pigeon Carrier solves all of this by supplying browser extensions for both Firefox and Chrome that allow uploading and hosting of files via Dropbox, as well as integrating preview functionality of pictures and documents directly into Twitter. For viewers without the extension, the attachments gracefully degrade into a short and simple website with a list of attachments.
