Reddit

Probably depends on how you define success with these things. The valuation of the company is down a significant amount since it was purchased and recent reports had ad revenue also down a significant amount too. Whether the owner cares about those things is probably up for debate, and evidence would suggest he might be looking for something other than money out of it, like influence, or just a play thing. I'm not sure the owners of Reddit are motivated by the same things, I think they just want to be richer. Time will tell I guess, it's difficult to tell the difference between incompetence and intentional acts from the outside.
