There is many awesome services on the net. Here, I present to you, some of them:
Uses WebRTC and Peer-to-peer technology. Servers are only used to kick off the file transfer.
Anonymous, volatile file sharing. Features easy, simple to use HTML5 interface (drag & drop). Anonymous for uploader and downloader. Volatile files: They are uploaded to RAM, disappear on your unsharing or closing the tab.
Were you ever annoyed about people using the utterly slow imageshack? Tell them to use abload. (The site is German – still, it’s the one I use. Great service.)
