A few thoughts on the past week:

• Looks like Twitter’s not going anywhere. The company just received a new round of VC funding.
• The sustainability of the iPhone/application business model – Interesting bit on whether iPhone apps are disposable.
  
• Scott Berkun’s new book – My friend and writing inspiration of sorts has his third book coming out in a few weeks. This one is on public speaking and, based on the success of his first two books, should do very well.
