There is steemgigs.org -- the FIVERR of Steem :)

I used eSteem android app to publish my first blog post.

And now I am typing this from steemitstage.com. I learned this from @steemdev :)

What I like about busy.org is the autosave. We will never lose our work in case of unexpected power failure.

What I like about eSteem is the SCHEDULE feature. We can save lots of drafts and set schedule for posting. :)

But for interacting steemit and steemitstage is still the best especially for mobile users.

For videos, dtube is the best.

For photography, I like steepshot but you need a good mobile with great picture resolution because I couldn't find photo enhancer there. I don't think I'd use it.

I might stick with eSteem if I am on android and steemit/steemitstage on browsers for security purposes - can login using POSTING key. Busy.org requires generated password to login so if ever you click hacker's link by mistake, goodbye SBD!
