I wouldn't call it a serious attempt to better Twitter. It seems too focused on mobile media, not desktop media; the only filetypes you can upload (jpeg, mp4, 3gp and xvid) are typically found on cell phones. But it hasn't come close to success (or even beta status, really) yet. There's no public API. It doesn't let you upload audio files. Its website needs a lot of work still for desktop usage and a mobile version doesn't even exist yet. Competition is great, but this doesn't look to be it for Twitter. Not yet at least.
