But not many individual investors were able to scoop up shares of the seven-year-old company at the IPO price. That's because the big boys -- institutional investors such as mutual funds and hedge funds -- grabbed those.
So the question is -- in 140 characters or less -- should you buy in now that it's trading like any other issue?
There's no easy answer, but we'll run through some of the pros and cons.
First, Twitter (TWTR) is off to a fast start. The initial offering of 70 million shares was priced at $26 dollars, and the first trade was at $45.10 a share. That's a 73 percent jump. Trading, no doubt, will be very volatile for at least the next few days.
Proponents like it because Twitter has become part of the vernacular, especially for people age 18-to-34 -- those most targeted by advertisers.
They live in the Twitterverse, sending out messages of up to 140 characters. Some are as mundane as what you had for lunch today. Others are earthshaking such as when Twitter played a key role in the Arab Spring revolution.
You can post your messages, and you follow other people who post. Entertainers Katy Perry, Justin Bieber and Lady Gaga all have more than 40 million followers.
The company has 232 million users worldwide, and its user base is still growing rapidly, up 39 percent from a year ago.
The IPO price was raised several times in the weeks leading up the Thursday debut here, but still came in at what analysts consider a reasonable level, at least in comparison Facebook (FB) and other social networking companies.
Now for some of the cons.
The biggest negative is that Twitter has never made any money; never turned a profit. And it doesn't expect to earn a profit until 2015 at the earliest.
Twitter is often compared to Facebook, but remember, Facebook was growing at a faster pace when it was the same size as Twitter is now. So it's public offering comes at an earlier stage of development.
Analysts say the company's effort to monetize its huge fan base is still at an early stage. It hasn't proven that advertisers can successfully appeal to its audience, and that users won't be turned off be turned off by too many adds.
And Twitter's pace of growth has slowed for seven consecutive quarters.
There are still plenty of skeptics who say Twitter could be a flash in the pan. They say there's no guarantee it will even survive.
The bottom line is, many advisers say there is no urgency to get into the stock right now. It's likely to be volatile of the coming days and weeks. So you might want to take a little bit of time to judge the company and its stock market value, before taking a leap of faith.
