Twixtr: Twitter for images?

Haven't had a play around with Twixtr yet but it looks like an image-enabled Twitter. Sounds good, but Dave Winer has some other thoughts:

"Twitxr throws down a challenge to both Flickr and Twitter.

To Twitter: Scale, scale, scale and add payloads to the API.

To Flickr: Go ahead and do an event streamer for pictures."
