Jive.ly is a new app in full beta, billing itself as a Twitter-like site for mobile. Created by UK-based developer Martin Buhr, the app is designed as a place to update your social network accounts with images and videos from a mobile. But since it has it’s own Twitter-like ‘follow’ model it’s therefore another attempt – probably doomed – to take on the site at its own game. But then again, Twitter doesn’t do MMS or auto-embed content from Youtube, Vimeo and Flickr from posted links and synchronise with your Twitter and Tumblr accounts.
