Whaleshares only just opened up in August/September, so it's still a very new platform. Officially no longer Beta, and they hyped it big in advance as well - mostly on Discord. So far, I'm very happy with it. Lots of Steemians there. Due to the big push here, I had the happy experience to start as a minnow, which really is cool. There's a lot to like there and the Masdacs site does a great job in crossposting to both Whaleshares and Steemit.

WeKu is an Asian-oriented site, which only opened up to the English speaking world in the past few months. It's a bit more active than Whaleshares, but technically still Beta (like Steemit) - it's almost a copycat of Steemit with minor differences. Very friendly community and no problem with reposting your Steemit posts there - though they prefer it if you mention that it's a repost. (This is also why I'm clear about my crossposting as well.)

I wasn't too worried about you not being calm - it was just the main image on that post that I was referring to. You should see your RC restoring fairly quickly, but yes, we all saw the worst drop on the first thing we did on Steemit after things were moving again.
