How many items are listed in Google Base?

Google Base is a free Google service that lets you publish any kind of information. It doesn't matter if you're a business or not, you can simply publish any item - be it a news about Pope Benedict XVI's visit in US or a review about a new product like Apple I - you can publish it if you have a Google account. You can login and already start submitting items from these categories (or if not you can create a custom category for a particular item you want to have published): Events and activities, Recipes, Real Estate ads, Reviews, Jobs, Services, Personals, Travel packages, Products, Vehicles for sale, News and Articles, Course schedules, Wanted ads. Once you're logged in, you can submit an item via their web form (or using bulk data feeds if you have more than 10 items), and if it's processed it will appear in the Google Base search, Froogle (if it's a product) and even in Google itself as a Google OneBox suggestion.

Anyway, Google Base it's a good way to have content promoted for free (be it products, services, ...) but I wanted to know how popular is it in terms of items that it has - so, because of a small glitch in Google Base, I was able to find out that there are 1,790,919,232 items submitted. The glitch I mentioned is performing an empty search in Google Base - that simple. If this is corrected on other services like the main Google web search, they didn't correct it in Google Base, so when performing an empty search you'll see to the right the number of items it searches through:
