Silent no more, El-Erian takes to Twitter

Just days after his noisy exit from Pimco, Mohamed El-Erian has joined the round-the-clock cacophony that is Twitter.

The former co-CEO of the Newport Beach, Calif., bond giant posted his first tweet Monday morning at around 10 a.m. to announce his presence. He officially left Pimco on Friday.

By late morning, El-Erian had busied himself posting four tweets, indicating he's not joining simply as a lurker. He admitted he had been hanging around Twitter just reading what others say, but is now ready to "contribute to cnvrstn," apparently using shorthand for "conversation" necessitated by the microblogging site's 140-character limit per tweet.

His entry to the twitterverse did not go unnoticed, as he racked up 5,000 followers in just a few hours.

Since announcing his departure from Pimco, El-Erian has been mostly silent, contributing a few op-ed pieces here and there but not addressing the reasons behind his move.

That has left Wall Street and the media to speculate, with stories aplenty that a widening rift with the firm's founder Bill Gross accompanied his exit.

El-Erian has declined multiple requests from CNBC.com for comment.
