Comscore came out with new numbers yesterday and Twitter traffic in the US has grown like wildfire. In February, Comscore rated Twitter traffic at 4 million US users.
Then yesterday, they gave us this:

Unique visits to Twitter.com in the US jumped from 4 million to 9.3 million in March. That’s a growth of 131% in one month. Wow!
Nielsen and Comscore both chime in on the age ranges, concurring that ages 25-54, in general, are the tweetiest. Here’s what Nielsen has to say:
Twitterers (a.k.a. Tweeters) are not primarily teens or college students as you might expect. In fact, in February the largest age group on Twitter was 35-49; with nearly 3 million unique visitors, comprising almost 42 percent of the site’s audience. We found that the majority of people visit Twitter.com while at work, with 62 percent of the combo unique audience accessing the site from work only versus 35 percent that accessed it from home only.
It’s worth noting that these numbers are all for Twitter.com. They don’t take into account the folks using desktop applications or mobile access.
With numbers like this, brands shouldn’t be ignoring Twitter any longer. Now I suppose the question is, has Twitter hit its tipping point? What do you think?
