When I started listening to EP, around episode 70, it was posted on Wednesdays. Then it started creeping into posting on Thursdays, and now it's creeping into Fridays. That's just the way it is, I think - Steve seems to work on weeks which are slightly longer than 7 days - maybe 7.05 days or something - and until we can get the government to institute a leap day in every 40 weeks or so, we'll just have to accept that EP posting time shifts.
