I left a corporate marketing job in November of 2007 and never looked back. I have been buying domain names since graduate school (circa 2002) though. I probably got serious about domain investing in 2006 or so. It has been pretty thrilling to build my business. Lots of ups, plenty of downs, but overall, it has been a great decision.
It would be interesting to know how long readers have been buying domain names as investments. Participate in the poll below to let us know how long you have been investing in domains.
