It is good you finally made it on here. You are right, STEEM has a lot to offer.
To support the STEEM ecosystem, I suggest a few different applications. There is D.Tube where you can post your videos in addition to Youtube. I would also suggest using the Busy.org interface at times. There is a twitter like app called Zappl which is nice to send out quick message. We have a new reddit like app called parley.io.
If you need to do some live broadcasts, there is Dlive. We also have dsound for your audio productions.
Essentially, there is a wide array of social media apps to fulfill all your needs under one roof. As this platform grows, you will see even more development and users. It is growing at a terrific pace.
Thank you.
It is good to know there is so much here and those other applications will be used as we can. Our goal is to support STEEM in whatever ways we can.
