When did you find yourself getting most of your coding done? Mornings? I'd love to try something like this, but it will probably mean writing code at like 6 am..
Personally I like to do my side coding project in the evenings. I find that if I do it in the morning it's too "all consuming" (I'll end up working on it to the exclusion of my main work.) For me morning/early afternoon is my prime coding time so it feels right to devote those hours to my job. I concede that the weekday side project code won't be the most amazing ever, but it's something and it's moving me forward.
