My 2 cents (that's the value of my vote currently xD)
But I will very shortly be delegating my HP to start earning LEO tokens.
Creating content - Most creative
Community tokens - Most social
Gaming - Most fun
Market trading - Most intense
Curation - Most relaxing
I like & agree with your list assessment. I have delegated some to the Inleo community for the exact same reason as you are going to. Out of all the created frontends / community tokens I think the LEO Token is the best bet to be a success.
