Hot twoppic of the moment is the company SharesPost who just released an index putting a monetary value on prominent social media sites. It put the value of Facebook at $11.5 billion and the value of twitter at $1.4 billion. The Wall Street Journal reported that Facebook will likely go public in 2011, and financial analysts predict that by then the company will be worth $40 billion, proving once more that social media is a booming business.

Today, you are encouraged to embrace your inner nerd -- National Grammar Day is here, and your hot twoppic of the day. The Society for the Promotion of Good Grammar established March 4th as a day to "March forth to speak well, write well, and help others do the same!" It was made a popular trending topic because people were retweeting a tweet from comedy website @funnyordie, who said Celebrating National Grammar Dayon Twitter is like trying to hold an AA meeting in the middle of Mardi Gras. Tweeps are also posting links to grammar quizzes and grammar tips.

Twitter cannot get enough of Justin Bieber, and with the release of his new album My World 2.0 only a few weeks away, the tweeting has reached fever pitch. This morning Bieber dropped his latest track on Ryan Seacrest's radio show, called "Eenie Meenie" which features singer Sean Kingston and his island pop style. And Justin might just gain new fans with this one: @mikeljohnsan: tweets cant belive it, well okay i never really hated justinbieber but i never liked him either, but Eenie Meenie ft. Sean Kingston is AWESOME.
