During last few years I have been involved in a number of projects. Some of them have failed, some succeeded ;-)
The most recent project, quite likely to become a great success. Wikidot.com is a free wiki hosting service that allows you to start your own Wiki.
Business project to create a financial backbone for Wikidot and a few other related projects. Not finished.
An open-source release of the Wikidot.com software. Quite likely to succeed but requires a lot of work.
OZONE Web Application Framework
A PHP Framework for building advanced web application — just like Wikidot. Uncertain future — quite likely to become an integral part of Wikidot.
Distributed, large scale computing in Java. Never finished and rather a failure.
