It takes longer to find gems than the last 7 days.

Exaaactly. With the 7-day limit Steemit is more like a news site, isn't it. It's rewarding to post and curate content relevant to current events.

I think the platform could work if you already have a large number of followers who already have a lot of SP. But probably not so great about building a following from scratch. I donno, Steemit is a really really cool idea, but a lot would have to change before I consider investing time and effort here.

I also wish you luck with integrating it into your creative presence on the web! Maybe you'll discover a totally new paradigm and we can all copy you. :D
