San Francisco (ip-192.com): You can Tweet on and enjoy the weekend – Twitter is set to raise about $100 million of new funding that would value the company at around $1 billion. This is remarkable since Twitter has big plans but no discernible revenue yet. However, the 60-employee company is teetering with advertising on its website to generate some much needed revenue.

After only 3.5 years, Twitter attracts approximately 54 million visitors per month. To sum it up, the bet is that Twitter will continue to grow exponentially and develop into a rich new source of business intelligence, a channel to reach targeted consumers around the world, and a breathing ground for marketing and news startups.

Twitter users are twice as likely to click on advertisements, according to a study from research firm Interpret. They are also twice as likely to visit company profiles as consumers on "traditional" social networks such as Facebook and MySpace.  So, you may just get used to advertising on your Twitter page. If it doesn’t come in 2009, it will come in 2010.

Until then, Twitter has a lot of home work to do. Frequent outages still plague the company, and frequent users complain that the micro-blogging site does not allow editing after submitting a Tweet. There is also no way to permanently delete Tweets, or receive a daily or weekly e-mail digest summarizing new followers and unfollowers. The biggest complaint still comes from power-users that can hit Twitters API limit of 150 calls per hour easily.
