well its too early a call, but one thing is it is not unsuccessful... you are all aware with the limitations (eg comet support and cron jobs being the biggest)

well its too early a call, but one thing is it is not unsuccessful... you are all aware with the limitations (eg comet support and cron jobs being the biggest), but it is still not bad for quick prototyping and even releasing sites with medium levels of complexity (ive written a simple chess site - wizchess.appspot.com - does the basic game play and all but lots lots lots of polish required)... but it certainly goes with google's philosopy of "fail often, fail early" (or the other way around).. essentially they are developing the api in tangent with developers who require new features though it has been slow late i think...
