Why is everybody starting on Tuesday?

This account is just three days old; I signed up for this site three days ago after having lurked around for maybe a year now. One trend that keeps popping up that I can't shake off: it seems like almost all launches that I have clicked into were actually launched on either Tuesday or Wednesday. Is there an actual strategy that lies in this, or am I seeing things because those are precisely the days that I browse?

I checked out a few maker posts and there have been mentions of "avoiding Monday and Friday" but never an explanation of the logic behind that apart from the phrase "more traffic." More traffic compared to what — Thursday? Weekend?

Has anyone here launched on this site previously? If so, was your choice of day of the week deliberate or was it a coincidence?
