Right, that makes sense.

Once again, this is excellent advice! Thank you for anything you can do
for the domain.

What's the usual way to generate sitemap.xml files? Would be great if it
was automatic somehow. Do the files benefit from hand editing?

Several Scheme implementations already have articles on the English
Wikipedia, and the articles display to the implementations' homepages
URLs and link to them. If some of the URLs were *.scheme.org, that would
be very nice. It also means a lot of reputation is riding on the domain
so we need to do our job well :)
