Twitter updated their privacy policy. Some highlights from the official Twitter blog post:

Today, we’re announcing a suite of industry-leading tools to give you more access to your information and greater, more granular control over how it’s used. We’ve also updated our Privacy Policy to reflect the improvements that we’ve made to Twitter.

And:

We’re expanding Your Twitter Data to give you the most transparent access to your Twitter information to date, including demographic and interest data, and advertisers that have included you in their tailored audiences on Twitter. Each category of data will be clearly marked, and you will be able to view or modify this data directly.

There’s lots more to read in the blog post, but the changes to Your Twitter Data are worth exploring.

• Here’s a link to Your Twitter Data.

Take a few minutes to look around at all the data Twitter has collected on you. There’s a lot of odd data in my set. For example, here’s the list of languages Twitter has for me:

French, German, Slovenian, Indonesian, Basque, Dutch, Turkish, Spanish, Estonian, Portuguese, Tagalog

That’s certainly not representative. Not sure where these come from. Languages of people who I’ve interacted with?

Also interesting is the list of Interests further down the page. This was somewhat representative of my interests, but not exact. I wonder how this list was built.

Another interesting collection is the “tailored audiences” section. From mine:

You are currently part of 6624 audiences from 1573 advertisers.

Not sure what that means, but if I cared to tailor my advertising experience, there’s a button to “Request advertiser list”. I might dig into that at some point.

Take some time to look over Your Twitter Data. Good to know what choices you have.
