In the general population, “Mono” may be best known for infecting teenagers with the “kissing disease.” On the Linux blogs, it’s recently caused a different kind of anguish as geeks far and wide have debated whether it’s infected Linux too.

It all started earlier this month when Linux Canuck posted an explicit description of why he — or she — dislikes Mono and is consequently considering abandoning Ubuntu.
