Compete.com is pretty good
Comparing website traffic with Compete.com. The primary website is not included in this though. Pretty good for indicating trends, but kinda useless when assessing real, day to day, traffic volume.
The Analytics data is only from this website. Normal traffic went from 30 uniques a day in 2009 to 150 in 2010 with short spikes of 2000-5000 uniques per day. 50 percent of traffic comes from search engines.
