Still Wondering about Google Base?

If you - like me - are still wondering what this Google Base thing is actually used for and if there really anyone that uses it, this post has some answers for you:

So what is Google Base? Part shopping directory, part recipe search service, part classified service.

Hitwise market share data shows that Google Base, after a fairly strong start, received approximately the same market share of visits for the week ending April 1, 2006 that it did a month after launch.

Sadly they don't have absolute numbers for Google Base usage, but they say that 0.0017% of US internet visits are to Google Base. Can't really tell if thats much or not ... but if I assume 80 mio US-Americans using the internet on any given day, on average each doing 30 visits (what exactly is a "visit" anyway?) this would come to ~40000 visits/day.
