Enclosed below is the April usenet ratings report for selected *.os.*
groups. It estimates alt.os.linux readership at 23,000, and
comp.os.linux readership at 20,000. comp.os.minix is still ahead at
43,000, but I predict this won't last long.

Make of this what you will,
-al

(I just realized I left out all the comp.unix.* groups. Whoops.
You'll have to check the original article yourself if you're
interested.)
