<h1>Back then I said..</h1>
<blockquote>
"My pet bugbear with WebGUI is the hurdles it places in front of the do-it-yourself hobbyist
web crowd, who also happen to be the people most likely to write blog articles and generate
buzz around the project.
</blockquote>
<blockquote>
... it's frustrating to think that so many more people could be getting excited about WebGUI
if it was only easier and cheaper to deploy.
</blockquote>
<blockquote>
Now if someone could just figure out how we could do that.."
