iseff: Introducing Openomy

It's time to introduce Openomy. It's far from complete and I have a lot of work left to do, but I want to get feedback as soon as possible, so let's start with the concept:

In short, Openomy is an online file system with an open API anyone can use to develop applications to meet their needs.

I think Openomy can be best described in more detail through the concepts which derived it. I'll break this up into three distinct concepts,

1. Openness and APIs,
2. Tagging, and
3. AJAX.
