Twitter’s filing for an IPO last week has sent the real estate market in San Francisco soaring. San Francisco was already one of the most expensive cities in the country. Now it’s going to be untouchable. Twitter is located right in the heart of the city. All of a sudden, many of the 2,000 people who work for Twitter will have plenty of money to plunk down on fancy digs.

A real estate agent friend in SF told me that smart brokers have been romancing the upper echelon of Twitter to rep them in their pursuit of new, upgraded homes. More Twitter employees then would like to admit have been looking for residential real estate for the last six months. The better properties are going to go fast.

Mention the name Twitter to anyone in the Bay Area — the digital community, investors, writers, TV producers, celebrities, comedians, politicians, and Twitter users — and you’ll get a big smile. Twitter has changed our lives. It has been a public platform for everyone who wants to make a statement or vent and is one of the most important resources for up-to-date news and opinion.

Now word has it that everyone who is involved with Twitter’s IPO is very concerned that the content posted on Twitter stay relevant and personality driven. It has to remain a main attraction in the news arena in order for it to constantly be appealing to the investment community.

Twitter reportedly had an average of 218.3 million active users a month in the second quarter of this year, up 44 percent from the same quarter last year.

The New York Times recently reported that Twitter expects its growth rate of users to slow down in the United States as the service approaches market saturation. Twitter is hoping to get its future growth from markets like Argentina, France, Japan, Saudi Arabia, and South Africa.
