I agree, there's going to be a lot of competition. But that's good for the user, as it means better services.

Steem is already out ahead of everyone else. Be nice if they can stay there.

Popchest looks pretty straitforward. More of a competitor for youtube than anything. It doesn't have the aggregation aspect Steemit does anyways. Not built off the blockchain either (admitedly that only matters to/is understood by a really small percentage of the population). But they have a site up, which is more than a lot of these companies can say.
