Immediately after the HTML5-loving Tizen project was announced, many MeeGo community developers and other stakeholders weren't too happy in the situation -- for the outlook of the proposed OS itself or how the announcement was handled, Many MeeGo developers were looking for a new community alternative.
Well, with a few months having passed, a former MeeGo developer blogged his side of the status update.
The status update basically comes down to: Tizen is still vaporware with membership being basically invite-only, the official Nokia Maemo platform is no longer actively developed but there is some community left, and MeeGo as a project itself is also basically deceased. There is though some work around the Mer Project as a community-based project with similar intentions to MeeGo.
Last I've heard is that the first Tizen development release is likely to come this quarter -- perhaps hearing more next week in Las Vegas at the Consumer Electronics Show from Intel and other vendors.
