I'm not sure this solves any particular problem that <i>I</i> have, but there are enough interesting ideas here (like the lightweight form generation) that I think are worth looking at. Definitely not just a clone of Sinatra or web.py.
Some interesting ideas, and I love the conciseness, but..:<p><pre><code> [:title_x60, :text_60x10]
</code></pre>
.. made me throw up in my mouth a bit. I like some of the ideas but this is the sort of janky Ruby that unfairly makes other people go <i>"See, this is why Ruby sucks."</i> Nothing that couldn't be cleaned up, of course :)
