Edited sentence: Boron is the code name for the next generation of Nucleus.Due to the flexibility of the basic design some people have taken to using Nucleus as a simple content management system to which it seems to lend itself very nicely.Even so the current 3.However, this large collection of plugins is not the central selling point of this system.It is a not-in-a-hurry planning project that might one day be Nucleus 4.It is offered as part of Fantastico by cPanel web hosts and has an elegant plugin system that leaves the core strangely lacking the more common "growth bloat" of other products of similar stability.It uses a Call back system to generate "events" which can trigger plugins (which provide an extensive range of added value).Other keen features include blog by mail and a blog-roll manager and a powerfull bookmarklet for blogging on the go.The practicle upshot of this development is that several new framework style plugins are now planned and a new handshake protocol is also being developed for plugin developers to use that should enable plugins to talk among themselves.The thing that attracts users more than any other thing is the strength of its community.The trim (if patchilly document) core uses a PEAR like call back system of "events" that plugins can subscribe to.When people discuss NucleusCMS online the talk inevitably turns to the great and friendly support offered in the forums.Which has led to everything from wiki-style markup to trackback that was spam resistant from the start (it worked with the anti-spam plugins).While Boron might be miles away a new collection of powerfull building blocks are just arround the corner with the development of a number of "enhanced standards" such as Extend Aware which aims to provide a higher standard to aim for when developing plugins.While not one of the biggest and most wideley adopted blogging platforms it's word-of-mouth-only promotion hides a wealth of understated potential.x will be maintained even after the release of Boron (when-ever that might be)
