Since my hobby (sailing) requires reasonably nice weather, and since it's getting damn cold here, I find myself more and more often working over the weekends too, reading or housekeeping.
What do you folks do over the weekends when the requirements for your hobby aren't satisfied?
As for your question about weekends, i am in a doomed profession which requires me to give certain exams (so is my wife).. so we end up studying on most weekends :)
So generally I spend Saturday doing an end-to-end test in our pre-prod environment to make sure everything looks fine, and then I tell capistrano to do the release, and then I go and perform such standard human activities as spending time with my girlfriend or doing a little bit of sport.
None of my competitors and potential competitors work. People are nicely surprised to find a new feature or two working when they come back on Monday. Gives your site a sense of momentum.
