Glad you were able to check it out. I prefer the layout and features of Busy more, but SteemIt has a dark theme that I love. I can't stand all white backgrounds. The multiple websites that load the Steem Blockchain's content is one of the things that keeps the Steem ecosystem from being censored or taken down. Even if someone is able to take down SteemIt's servers, we could all still simply login on a different front end.

The "Thumbs down" feature on busy is equal to "flagging" on Steemit. That is simply a down vote that can make posts earn less and also have less visibility. One of the jobs of being a quality curator is flagging Spam posts and comments, but I personally don't flag users who have a large amount of Steem Power due to the potential of them retaliating and flagging me back.

Yeah invest whenever you feel ready, and until then simply invest your content and your time :). This platform has the potential to really be amazing if we can get more and more of our network converted here.
