LooseLips is an alpha release of a post only Twitter client. The idea behind LooseLips is to quickly share photos, links or other content. By focusing on the posting experience LooseLips already offers some useful capabilities:
- Shorten a URL just by clicking it. You can restore the URL by clicking it again.
- Share a photo by dragging and dropping to the post area, or by copying and pasting.
Download LooseLips

I'll update the download link with new versions as they're released. If you try out the alpha please get in touch to let me know about problems or to provide feedback.
(Updated 2010-04-11: Should have mentioned - supports XP SP3 or better. You need .NET 3.5 SP1 installed - you can pull this from Windows Update if you don't already have it.)
