Yes we did take a mini-loss with ETM.com - but it's 1 very small rock in an ocean of domain sales.
We move a serious amount of inventory each month, 95% of which is (highly) profitable. Why waste time/energy pondering over the 5% setbacks. It happens, we move on. Our model is churning out constant sales each week and that's what counts. But most aren't able to look behind the scenes (thanks for taking a peek jds626x) so they focus on that one negative setback.
75% of domain investors are investing at a loss / not profitable - so I think we're doing OK.
