I don't know if you know but i am working on an already pretty mature project called "BloxPress".
It is based on my first ment-blox drag/drop theme i started with. After a while i decided to discontinue the work on that theme because the project was gone to be a much bigger thing then ever planned.
BloxPress is an Web 2.0 Theme Framework for WordPress.
It's fully compatible to any WordPress 1.5.2 vanilla install. Just throw it in and you are set.
What's Web 2.0?
in short terms: "This â€œWeb 2.0â€³ thing puts the content in the hands of the user.", in BloxPress your user has full control of the entire content-layout and is also able to save/reload it and to choose from your layout presets.
Why it's supposed to be Framework?
I wrote an own theme engine within the theme environment of WordPress enabling designers to take advantage of the latest technologies. -> On-demand content loading over AJAX.
The whole project is too huge to put in this little textbox: Best thing you can do is to visit the dedicated site and read thru the docs.
This is something completly different and hands a lot of power to Bloggers, Visitors and Designers.
There will be BETA-Releases in a few, but what i really could need right now is some feedback on various aspects of my concepts. Theres a Project-Chat forum for this purpose and also feel free to comment the latest news.
Feel free to suggest features in case you are missing something. I will add anything of use!
Thanks, and i hope you like it.
