I track my net worth monthly on NetworthIQ.
By end of March 2011 our net worth was $646,381. This is down $1,491 from the previous month in February.
Our cash balance went up quite a bit as we got a year end pay out from some rental income. My stock value dropped because my employer stock value went down. Our retirement accounts were up a couple thousand. Unfortunately the value of our real estate all went down yet again and that alone undercut all our other growth.
