Google Public Data Explorer

Recently I came across another significant feature made available by Google. Google Public Data Explorer. Apparently, as per googleblog, this feature has been made available or googleblog has been making public data available to user since last couple of years :-) Nevertheless, now researchers, students even naive users will have one single place where data like...
1. Country-wise GDP
2. Statewise Unemployment rate in US
3. Various data released by autonomous bodies, international bodies like IMF, etc
etc

• Even more to feature is; These data can be visualized in various forms like charts, etc
• One can add his own data conforming to open standard like Dataset Publishing Language (DSPL) which is in a xml form (I guess, publishing of such submitted data would ultimately subject to satisfaction/approval of google team)

I am yet to explore it further. But somehow I feel, though with this feature google has made available users; an utility to access publicly avaiable data; to me, it can also be seen as an encirculment attempt

where, the facilitator will store data & will get it growing over the period. And once data grows over the period, it becomes an asset to organization on which it can easily capitalize. And Google is well known for this :-)
