You may have a point.  But it comes down to uneven enforcement.
Twitter smacks down an app because they allow an individual to recur,
say, every Monday: "Today is Monday and my office hours will be from
2:15-3:30pm".

Meanwhile, you have apps which do things like this:
http://search.twitter.com/search?q=%23fun140

Aren't those effectively recurring tweets?
