Twitter Asks Ad Tester Not To Talk About Testing Twitter Ads

We now have a pretty good idea of how Twitter’s ad products work. How do they perform?

You’d have to ask companies that have tried them out. One Twitter ad tester, VoIP platform CallFire, would like to tell the public. But Twitter has asked them not to share.*

Here’s the beginning of a blog post CallFire marketer Natalia Klishina published Wednesday:

Towards the end of 2010, CallFire was invited to try out the beta of Promoted Twitter. I had originally written a blog article explaining the service and reviewing it. Unfortunately, this article has been removed due to Twitter’s informing us that “during the beta rollout of [their] Promoted Products services, advertisers can’t blog about their experiences using the products.”

And then Klishina inserts this clever retort:

No comment from Twitter.

*To be fair, asking beta testers not to talk publicly about beta tests isn’t unique to Twitter. Google, for instance, does the same thing.

I think the NSA has a job to do and we need the NSA. But as (physicist) Robert Oppenheimer said, “When you see something that is technically sweet, you go ahead and do it and argue about what to do about it only after you’ve had your technical success. That is the way it was with the atomic bomb.”
