Overall I think the trend has started back on an incline, but I wouldn't say its anything like last year or even a few months ago. Between ND, Parked, Adsense, and Sedo I was averaging $12 daily. I've bought a few traffic names, and launched a few minisites since. Right now I'm averaging about $5 a day. Thats actually up a bit from where it bottomed out. For a while it was below $4.
It sucks that revenue is so far down, but it has been a good experience. I set my sights on $100 a day to take domaining full time. If I had approached that goal and quit the day job this little bump in the road could have really hurt. Now I've got a much better idea of how low the bottom could be and just how much of a safety net I need before I leap into becoming a full time domainer.
