Reddit raises $300M at $3B valuation

You're right though: things can change. But they usually don't do too quickly once the dust has settled and the giants have emerged. Yeah, yeah, there could be a Google killer tomorrow, but there probably won't. That's very different when markets are still developing and nobody has any clue what's going to happen in 6 months time, but monopolists don't just disappear over night because a new kid rode into town. That's what's different between snapchat, myspace and facebook.

Reddit has nothing even close to that kind of pull. To get to the advertising dollars, it will have to crack down on users and become sfw, and that will turn lots of people away. When there's money to be made, they will also have to deal with copy right, and that will shut down a good part of the meme subreddits, I'm afraid. I'm sure it'll still have a place in a few years, controlling a major discussion platforms is worth money after all, but I don't see it going to the big league by staying what they are now.
