I'm very pleased that my prediction came true regarding usage of LMDE. If you look at my posts in September/October period, I predicted that by the end of the year LMDE would move up to become the 3rd most used Mint Edition (based on registration on Community Website). I don't really look at "64-bit Edition" as an edition; to me it is more of an architecture variation that can apply to several different editions. In my eyes, LMDE has moved up to second position behind the Mint Main edition in usage. Looks like LMDE is difinitely here to stay boys and girls.
Congratulations to Clem and Ikey on the success of the LMDE experiment.
