By this point, almost anyone worth following is already on Twitter, including politicians, celebrities, countries, news outlets and Rebecca Black.
But as 2012 quickly approaches, there are still those who are either new to Twitter, are using the technology in new ways, or will be especially interesting to follow as the new year develops.
Essentially, Alan Sugar is England's Donald Trump, although he is considerably less ridiculous. He is the host of the English version of The Apprentice and is a shrewd businessman who built a billion-dollar fortune from nothing.
He also loves soccer, is a supporter of the Tottenham Hotspur and regularly chats with English footballers.
But above all else, the reason to follow Sugar is for his ongoing feud with English journalism cum CNN host Piers Morgan, whom he tongue-lashes (tweet-lashes?) every chance he can get.
A new, random Swede will take control of @Sweden every week, becoming the sole ruler of the world’s most democratic Twitter account, as its Web site says. The curator has a full seven days to post whatever he or she pleases without censorship, in English.
This week, Anders, who lives on a farm and likes to hold roosters, is in control. He has sent out hundred of Tweets and has dutifully responded to a number of followers, as well as taught the world about hunting boar and his homeland's love of corn on the cob.
Following @HSMPress might land you on an FBI watch list, but there is something fascinating about watching live battles between rebels and government troops in Africa unfold in 140 characters. (At least its fascinating to political journalists, who made up a good percentage of the group's 6,000 followers).
HSM stands for Harakat Al-Shabaab Al Mujahideen, the official name of Somali terrorist group al-Shabab. While it is generally a propaganda tool, the feed gives live updates and commentary on ambushes, IED attacks and gun battles.
HSMPress also regularly taunts the Kenyan military, which is currently on an offensive to push al-Shabab deeper into Somalia, as well as uses the feed to criticize the Eritrean army and even the New York Times, which it eloquently called professional amateurs whose good measure of propaganda & lies seem to be the sine qua non of their bizarrely fictitious masterpiece.
Like Sweden, Al-Shabab also regularly talks to followers and seems more than willing to answer questions, even ones about militancy and murder.
While the account hasn't been verified, it is considered to be genuine. Above all else, having terrorists on Twitter is a zeitgeist that cannot be overlooked.
The Occupy Movement
There are a number of different Occupy feeds that you can and should follow. After mass evictions around the country, the media has remained relatively quiet on the movement, but Occupy is still active and still protesting, including its Christmas Day mass in Zuccotti park and the Occupy Our Homes initiative, which is putting families into vacant homes foreclosed by banks and fighting evictions in court.
As Occupy gears up for a spring and summer rife with activism, follow OpWallStreet, the international account for OWS; TheOther99; OccupyWallSt; and your local Occupy group, be it Boston, Atlanta, Portland, etc.
If you're going to read one online newspaper in 2012, why not make it the IBTimes?
But seriously, follow IBTimes for in depth analysis on the 2012 presidential campaign, as well as news on global business and world politics.
Ed Husain is the Council on Foreign Relations' Senior Fellow for Middle Eastern Studies and provides intelligent updates on the politics of the Arab world, which is especially important as Egypt, Tunisia and Libya test new governments and experiment with free democracy.
Ron Paul Newsletter: 140 character excerpts from the now-infamous newsletters sent out and signed by the Republican hopeful in the 1990s. Paul has disavowed the letters, saying they were neither written nor read by him, but the hate, racism and homophobia spouted in the Tweets are simply unbelievable nonetheless.
