Very true Quacka. And note the enthusiasm of monetizing their sites?. Advertising!!
You can bet that THAT is Dom's ultimate goal, not Track, not debt, HIS products and sticking an ad in every Q&A.
If Adam D'Angelo can do it, you can bet that Dom can. But, we're talking 8 years with QUORA with little quality opposition and HEAPS of CRs, $168 million raised in last 3 years!!!!!
