There are two versions to the release – a full version that includes a number of pre-installed socnet features (bookmarks, blogs, messageboard, status etc) and a core version that allows anyone to build their own social network on top of it (think ‘layers in an onion’).
Version 1.0 comes after three years evolution of the codebase since Elgg was initially released in 2004 as vers. 0.1.
The guys at Curverider have emphasised design as a key factor in the build and they have also focused on user control as a key element. Co-founder and CTO, Ben Werdmuller, explains their thinking as follows:
Over the next few years, the explosion in niche social networks, and otherwise socially-enabled websites, will lead to new technologies that will allow you to federate your connections all over the Internet. This presents new opportunities for exciting new applications, but also opens new opportunities for your data to be abused. Therefore, you need to control exactly what is released, and to whom. That’s the core principle in Elgg.
