It seemed strange that Twitter posted this update on its business blog until the company mentioned that rate limiting has had a “minimal” effect on advertising. Many pointed out that limiting the number of tweets users could read per day would make it harder for advertisers to reach users and for Twitter to make money.
…oh, ok.
And no, I don’t really buy their excuses.
I believe the reason they couldn’t tell anyone in advance is that it was yet another ludicrously incompetent seat-of-the-pants decision by business genius.
