Zuckerberg told The Associated Press on Thursday that Facebook was working on giving users additional privacy options. The safeguards let users block from feeds entire categories -- such as changes to the groups they belong to -- while still allowing people to observe such changes by visiting the profile page.
The options were started Friday and essentially let users block all types of feeds if they want. Zuckerberg said Friday such options should have been offered from the start.
''This was a big mistake on our part, and I'm sorry for it,'' he wrote users. ''But apologizing isn't enough. I wanted to make sure we did something about it, and quickly. So we have been coding nonstop for two days to get you better privacy controls.''
