ALU Questionnaire Statistics

Lies, damn lies, statistics.

Data collected from http://www.xs4all.nl/~alemmens/alu/database/ as of 25th of July 2004.

There are probably errors in this, but hopefully not huge.

Implementation Choise

Only implementations that are "current players" have been counted: Symbolics CL, Lucid, KCL, etc. have been ignored. The ordering of entries is an ad-hoc attempt to make visual comparisons easier.

Lispworks and Allegro statistics include both paid-for and free versions. No weighting has been done ("a little FOO for portability testing" is worth the same as "mostly FOO"). Also, esp. for the current / near future category some entries indicated that the responder had not yet tried the implementation at all, but intended to (if such questionnaires are done in the future, I'd recommend clarifying the questions somewhat to produce better data).
