Almost half a billion people across the globe have signed up for Twitter, making it the fastest-growing social network in the world. Of all Internet users worldwide, 36 per cent, an estimated 485 million, have a Twitter account.
According to the internet research company Global Web Index (GWI), the number of account holders who use the microblogging site at least once a month grew 40% in the second half of 2012 to 288 million, the Telegraph reports. This figure means Twitter is growing faster than both Facebook and Google+, the report added.
According to the report, in the same period Facebook grew 33.4% to 693.5 million Google+ grew 27.7% to 343 million active monthly users.

And for getting followers, you need to have a really successful website. That means, if you already own a really nice blog with thousands of viewers, you can increase views by a thousand more by using Twitter. This is the only problem of SMM with Twitter
