The real service is Google Moderator: http://moderator.appspot.com/
TipJar is just a featured series on Google Moderator, just like the Shell is a featured application on the App Engine. It looks like Google 'seeded' Moderator with Tipjar, along with several other moderated discussions.
Here's my tip: neither the technology nor the content is interesting.
Sample: Pay your bills online to save on postage or Take advantage of free entertainment in your community – parks, museums, exhibits, etc. Go to free park concerts and other community activities.
Technically, Google Checkout is already a Tipjoy competitor. We worry about Amazon much more than G.Checkout & PayPal.

As it stands, a bunch of people could say, pledge $100/200/whatever each to a cause to make it seem like that cause has already raised a lot of money, causing people who might legitimately donate to go, "Hey, they've already raised loads. I'll give to someone else".
You can do this yourself on your site with: http://tipjoy.com/api/#extracting_transaction_data
You can use that feed to show, for example, only the recent paid transactions on your site.
On the subject of tipjoy, a useful option would be to allow people to just collect recipients that they are interested in giving to, and then split $10 or whatever between them at the end of the month. I think this would have two advantages: reduce the effect of Clay Shirky's micropayment decision cost problem, and allow people to budget more easily (which will make them less scared of giving money).
(I was thinking of doing this until I heard of tipjoy, curse you :-).
You'll find even if you use it a lot (3 times daily?), you won't get that much over $10 or $20 a month.
But I do agree such a setup would be pretty cool. We're building out some other tools, but this is a good idea, if done right.
