> There is nothing inherently different about App.net that would protect your privacy or guarantee you ownership The concept here is that by making their money from the users directly they align the users' interests with their own. > it will ring hollow once (if) they get big I suppose it's possible that they could decide they're not making enough money and convert to an ad revenue model. The problem is that there is already an ad supported service which is quite similar and free, so if they did that they would essentially lose all their users instantly. They'd also be violating their own core beliefs. I think they're a lot more likely to shut down the service from lack of users than they are to "sell out" in this fashion. I mean, there's nothing stopping Microsoft from shutting down the Windows division and focusing on Office for Mac, except that it would completely undermine their brand, and they make significant money from the Windows side. It's the same situation here: switching to an ad model undermines their brand and loses them their paying customers. Besides that, Marco's goal is to achieve profitability with a small userbase. I don't doubt that it's possible to do that, and it undermines the "they'll screw you over when they get big" concept because they are not, like most startups, trying to reach ridiculous scale before figuring out how to make money, which seems to leave the ad model as the only possible option.
