I cross-post from this blog to Twitter and sometimes LinkedIn, and on Twitter I follow a some interesting people. That means that Twitter by now have built a substantial dataset of what I am interested in and what kind of person I am.
I just checked and apparently, I am a nerd that likes tacos?
Reminds me of this. The list is very long and I think almost every phrase I have ever posted, retweeted or liked is there. If that’s the best Twitter can do, no wonder they have struggled to make a business out of it.
