Yahoo to Anonymize User Data After 90 Days
Found on Wired on Tuesday, 16 December 2008
Yahoo's announcement puts it months ahead of Google and Microsoft, which only begin really making data anonymous after 18 months.
In April, the E.U. Data Working party found that the large search engines were violating E.U. data laws and need to purge data within 6 months or explain very well why they need to keep the data.
This should put some pressure on the data-hog Google who would like to keep each and every byte you ever entered forever.
