You know, lurking is not a bad thing! You can get a feel for a community, see how people interact, and you can bear witness to some epic stuff along the way...
That said, I'm glad to see you're taking the plunge! Posting and interacting is a great way to grow your profile, gain steem power, and really get the most out of this awesome community.
I will say that even if you don't get the free delegation, Partiko is still the best mobile front end out there for the Steem Blockchain. The mobile notifications and instant messaging is the QoL enhancement that the Steem Blockchain definitely needed.
You might want to poke some of the awesome people in the @minnowsupport discord. They might be able to help you get a few SP to get yourself on your feet and able to interact. Especially if you're wanting to interact more.
