Chris Shipley publishes some readers responses to an article he wrote for the Wisconsin Technology Network
newsletter on the potential profitability of a number of Social Networking Services. Among the responses to his article
is the following from Scott Allen:
"In your recent article, 'Social Networks Revisited,' you stated that only Spoke has a clear path to revenue. . . .
ContactNetwork has slipped in under the radar - they haven't gotten a lot of press coverage, but they already have
nearly 20 paying customers and are cash-flow-positive. Ryze and Ecademy are both profitable, as is Craigslist
(technically, not a 'social networking site,' because you can't designate friends on there, but in reality a social
networking site, because that's what you do on there). Tribe also has a future revenue model that has been proven
already by Craigslist."
