Lady Gaga should be the first Twitter user in the site’s history to reach 30 million followers. Stats indicate that she should hit this major digital milestone in just under two weeks.

However, the amount of followers isn’t the yardstick by which to measure Twitter value. It’s the retweet that’s key, according to one of the site’s founders. So does the fact that Gaga amassed a huge amount of Twitter followers even matter?

Ev Williams, one of Twitter’s co-founders, said (quotes courtesy of TechCrunch), “The thing I think would be more interesting than followers is… retweets.”

He also said, “The dream metric is how many people saw your tweet.”

So essentially, Gaga’s ridiculously huge amount of followers isn’t that impressive. It’s how many people see, process and retweet her posts that really matters.

Earlier in the summer, a report came out suggesting that more than half of Gaga’s followers were either bot accounts or inactive accounts, and were therefore fake. So her 30 million followers is a bit of an inflated, flawed statistic.

Gaga may rule the Twitterverse from a sheer numbers standpoint, but Justin Bieber is nipping at her platform heels, and he should hit 30 million followers in less than two months. Katy Perry is right behind him, and stats and data indicate she’ll reach the milestone in just over two months.
