I'm pretty sure Yahoo did last year, but I remembered them posting a note about it before the week started. They haven't done that yet this year.
Obviously if you're in weekly lineup change HTH leagues, you have to pay attention to who's playing and make sure to adjust lineup accordingly. You don't want a pitcher that won't pitch, and if you have a decent player getting a few more games in, it might be worth considering benching a stud even.
In daily leagues the only thing I can think of from a "strategy" angle is to remember that it is a short week. That means if you have a bad pitching matchup, and don't need the innings to hit min IP you might be even more cautious, since you won't have as many other starts to lower your ratios if you do have a blow up. Same thing with hitters - if your borderline SB guys have good matchups early I might be tempted to start them over better players to get a couple SBs if possible, since a shorter week means it'll take less numbers to win each category. A shorter week may also cause you to look a little harder at your opponent's team and base decisions even more than usually on their team.
