While the fund may be old news, the departure comes as a surprise as previous reports had Arrington locked into Aol for 2-3 years. Some shareholders may be curious about what the restructured payout might look like. Those details have not yet been made public. This is the end of an era for TechCrunch and tech blogging as a whole as Michael Arrington was one of the earliest and most powerful tech voices. He was one of the first bloggers I met when I started blogging within weeks of TechCrunch launching in 2005, so we watch his departure with some sadness. But change is inevitable so the two things we’ll be watching closely are the future and evolution of TechCrunch without Arrington at the helm, and the future of the CrunchFund.
