That "first mover" line holds true everywhere so you're not wrong. Especially since it seems other blogging idea similar to Steemit are popping up everywhere. I signed up for a newsletter for something called "Civil" that looks to reward contributors in ETH. Looks very similar to here but more targeted towards journalists. Steemit is first so likely will be more rewarding since they're only talking about it and this is already up and running in beta.
