Ge.tt is a clever, instant file-sharing webapp that makes sharing files simple and fast. You can share a link to your file(s) immediately, without waiting for the upload to complete, and it doesn't use Flash, Java applets or any other plug-ins.
Ge.tt couldn't be easier to use. You don't even need an account to use it (though you get extra benefits from registering). Visit Ge.tt, click the Select files button, choose one or more files you want to share (drag-and-drop support would be nice here in supporting browsers), and that's it. Ge.tt will begin uploading your files and instantly generate a unique URL for you to share.
You can share the link before the upload is finished — files will update on the download page in real-time, as they're uploaded, and the user on the other end can start downloading a file while you're still uploading it. In fact, you can also add files to the share after you've shared the link. Any new files you upload will automatically show up on their end without reloading the page.
If you're sharing large files, we still think Opera Unite is probably your best option, but for the rest of your quick file-sharing needs, Ge.tt looks like an excellent tool for the job.
The terms page doesn't offer a lot of details on file-size limits, but it looks like they're currently pretty light on limitations.
