Advertisers came out against the potential ad deal between Google and Yahoo in a letter sent to the U.S. Department of Justice yesterday. The deal, announced in June, would allow Google to display text ads on Yahoo, with Yahoo deciding when and how the ads display and taking a cut of revenue. 

In its short announcement of the letter, the Association of National Advertisers stated the deal "will likely diminish competition, increase concentration of market power, limit choices currently available and potentially raise prices to advertisers for high quality, affordable search advertising."

Zoho has finally added a central document management page called Zoho Docs to tie together its many useful online apps. The clean-looking, functional page looks much like the Google Docs start page, with a folder view on the left and all files - spreadsheets, documents, presentations, etc. - listed on the right.

You can create folders and drag and drop files among them, and also right-click files or folders to quickly share, tag, rename, etc. You can also sort the file list by created time, modified time or document type (such as documents or presentations).
