The Twitter IPO is set to happen later this week and the buzz is already reaching a fever pitch. In fact, the company just raised its pricing range from $17-$20 per share to the $23-$25 range. The offering could now be valued as high as $2 billion and would value the company at just under $14 billion. Raising the pricing range by 25% is a clear signal demand for this long-awaited IPO is strong. I don't think it's a stretch to say this is the most anticipated IPO since Facebook - and you can be sure Twitter won't make the same mistakes. Another positive sign for Twitter, the uber-popular micro-blogging site is pulling teens away from FB. Basically, given the market and IPO conditions, the company likely couldn't be going public at a better time.
