MODERATORS
Yeah, I agree, especially towards the end where it gets harder and busier. I think it would have been better to do one challenge per 2 days, so that it finished at christmas eve, but I guess there is nothing stopping someone taking their time with it.
If you have one every other day, it's not habit forming, so I could see that reducing engagement.
Lol, its supposed to be enjoyable, not code-meth :)
But definitely a valid point. Maybe split part 2 of the challenge onto the second day? I guess we'll see how it plays out this year anyway.
