<p>trying to get a side project hobby going to keep me motivated from my 9-5 job on C# and was looking at Boo. some ?'s</p>

<ul>
<li>what has your experience being with Boo?</li>
<li>what kind of apps/projects have you done with Boo or </li>
<li>what is Boo capable of?</li>
</ul>

<p>Guess being the web world, would like to get my hands dirty with desktop applications etc.</p>

While it only uses Boo as the implementation language (rather than being fundamentally
about
Boo), have you read Ayende's "
Building Domain Specific Languages in Boo
"? It's not fully published yet, but you can get an early access edition.
I haven't had time to look carefully at Boo yet, but the
main
advantages over C# 3 (which gained some of Boo's features) appear to be terseness (lots of type inference) and metaprogramming.
