Therese Poletti posted a blog about the differences between twitter IPO and Facebook IPO. From the article, we can find multiple aspects how Twitter avoids the mistakes Facebook made before one year. Firstly, Facebook chose Nasdaq to start its debut. However, during the debut period, the Nasdaq computer system has collapsed which resulted in unsuccessful stock trading. This is why Twitter picked NYSE instead of Nasdaq. From the reference Twitter offered, we can see that it only plans to raise one billion dollars , which is much less than Facebook did. Since the amount of Twitter’s IPO is 16 times less than Facebook’s, I think the technical operation of this public offering might be much easier than Facebook IPO. Therefore, the probability of unpredictable fault, such as the breakdown of computer system, would be much less.
