+ and *BSD distributions. NNTP is not as widely-used nowadays.
+
+Why perl 5?
+-----------
+
+* Perl 5 is widely available on modern *nix systems with good a history
+ of backwards and forward compatibility.
+
+* git and SpamAssassin both use it, so it should be one less thing for
+ admins to install and waste disk space with.
+
+* Distributing compiled binaries has higher costs for storage/cache
+ space is required for each architecture. Having a runnable,
+ source-only distribution means any user already has access to all
+ of our source.
+
+Laziness
+--------
+
+* Stick to dependencies available in Debian main, this should make it
+ easier for potential users to install, and easier for distro
+ maintainers to pick up.
+
+* A list server being turned into an SMTP spam relay and being
+ blacklisted while an admin is asleep is scary.
+ Sidestep that entirely by having clients pull.
+
+* Eric has a great Maildir+inotify-based Bayes training setup
+ going back many years. Document, integrate and publicize it for
+ public-inbox usage, encouraging other admins to use it (it works
+ as long as admins read their public-inbox).
+
+* Custom, difficult-for-Bayes requires custom anti-spam rules.
+ We may steal rules from the Debian listmasters:
+ svn://anonscm.debian.org/pkg-listmaster
+
+* Full archives are easily distributable with git, so somebody else
+ can take over the list if we give up. Anybody may also run an SMTP
+ notifier/delivery service based on the archives.
+
+* Avoids bikeshedding about web UI decisions, GUI-lovers can write their
+ own GUI-friendly interfaces (HTML or native) based on public archives.
