I completely agree, and even posted this not too long ago. Very related to your post.

• App::tkiv - use this on a daily bases
• Config::Perl::V - used by something else in the background. Almost twice a week. I hope it will be used a lot more after the upcoming QAH.
• Data::Peek - use this countless times each day :)
• DBD::CSV - use it once a month, but test it more than that.
• DBD::Unify - use it on a daily basis, and I hope to be able to abandon it within the next year.
• GSM::Gnokii - unreleased. See here why. Used several times a week.
• Spreadsheet::Read - used inside other tools. Probably several times a week.
• Test::Smoke::Metabase - used once a week but hopefully more after the QAH. In development.
• Text::CSV_XS - used very very often. Probably over ten times a day.
• Text::OutputFilter - no idea how often this is used (by my colleagues and or our customers).
• Tie::Hash::DBD - used by our customers. Probably twice per year.
• Tk::Clock - is on all my desktops. All day, every day.
• VCS::SCCS - never again, I hope :) I used it to convert SCCS repo's to git.
