I've been posting some little things here, lately.
Not that I don't think moshiach is more of an abstract concept, but whatever gets people to do good in this world is fine with me. Any redemption I need will only come daily from conscious, daily practice, not from a dude on a donkey and buildings coming loose from their moorings.
Unrelated, sort of: getting a good place in olam haba seems silly to me. I'm not worried about the afterlife. A more sensible mythology might be that if you do good while you're on earth, those who love you will be well-taken care of after you die. 'Cause what good is living large in olam haba if your loved ones are dealing with a world of eek in your absence? That would be like watching a nightmare. Not for me, thanks.
