Open .gov sites have come a long way since the SEC EDGAR days.
Data.gov was a huge step towards open government. . The current budget crisis may leave any new open government/Data.gov initiatives on the chopping block.
However, in the next few months, Data.gov, along with a number of other data-related sites of the government such as USAspending.gov and Apps.gov, are slated to be shut down due to budget cuts. The current annual budget of $37 million will be reduced to $2 million.
In the meantime, open .gov sites like the new FCC.gov are being rolled out.
