Nascent Scheme success story: ourdoings.com

Being a devoted family man, I've only been able to spend fractional
nights and wends on my pet project, ourdoings.com.  However, thanks
to the expressive power of Scheme, that amount of time has proved
sufficient for me to create very useful photo blog software.  Once you
get into the swing of it, you can put up your digital photos and blog
entries very quickly.

Today ourdoings.com is ready to take paying customers.  This involves
setting up a dynamically created form correctly ($1 minimum fee plus
$5/50MB/month, all PostgreSQL-database driven), receiving Instant
Payment Notification (IPN) from Paypal, and then contacting the paypal
site, authenticating its SSL certificate, and verifying all the
payment information.

There are a lot of details I've had to work through.  Scheme has
helped me by allowing me to inline anonymous functions when I need
them, so as not to have to change gears creating a separate function
and then reorienting myself to the problem I was trying to solve
before.

For anybody who wants to try creating a site on ourdoings.com, you
currently can create text entries with it without paying anything.
You only have to pay before being able to put pictures up.  Let me
know if you run into any problems.
