I found an interesting web-hosted application called ProtoShare that allows you to create clickable and working wireframes very easily. It has all the HTML elements you would need to design a web application, like headers, text areas, form interaction and even drop-down XHTML menus. Once you have a design, you can share it with others. It also creates a basic, linkable template that allows you to preview usage flow and overall experience.
This screencast demonstrates how ProtoShare can be used to create wireframes.

So now someone has ported WYSIWYG HTML editors to the browser – great!
Sarcasm aside, it does look like it could be useful if you need to prototype websites, and easily share it online.
