SIAG is another spreadsheet application which uses Guile as its basis
and the developer of that doesn't show signs of stopping. :) I've always
been of the belief: "If it fills a need, write it!" Even though it may
be similar in function to something else, your application may have a
different approach that could open doors of opportunity down the line.

complete Guile functionality. Spreadsheets developed with Guile today
have the advantage now, and will be able to interoperate smoothly with
Emacs later on down the line. IMHO stand-alone Guile apps are a Good
Thing. :)

I think that depends on the needs of the individual programmer. But from
the FSF site I discovered the primary motivation for Guile was providing
a real stand-alone programming language, Scheme, for use in stand-alone
or embedded scripting applications. This has a whole bunch of cool uses;
you can change the functionality of an application, for instance, by
simply swapping scripts... no recompiling or messing with hairy
shared-library compiler options. A great way to look at how this is done
is The Gimp... it uses SIOD instead of Guile but the idea is the same.
