OK, let me see if I can answer a few questions for you.

(1) I think you will know best what your skills are. It may take a little while to figure out how you can add value to the blockchain, but keep talking to people, making your following, and you will find it eventually. For example, a good friend of mine @cryptocurator is very new too, and his strength is statistics...something that I'm not so hot at, but he loves (bloody accountants!). He's now adding value to the blockchain by being able to present information that helps people to understand and explain where certain things in the Steemit platform are at.

(2) My favourite apps are steem.cool, steemnow.com and steemworld. There's loads of them, just give a few a try out and see what you like. Of course you might want to get into the thriving discord servers as well, and find like minded people to talk to in real time.

(3) Everyones style is different. Some just post the odd picture, others (like me) are a bit more verbose. Some are short and snappy, others prosaic. I guess I'd encourage you to write the way you like to write, but preferably in easy to digest sentences. I think often 100 words can be as powerful as 1000 words. And if you can, think Videos where appropriate, as they tend to get a much better response. In terms of imagery, I think the more you can bring visuals to your posts the better they will be received, as long as it's not just imagery for the sake of it. Perhaps experiment with your own style.

(4) this is the wild west. You can giveaway what you like. If people want it, they will have it. Be aware that advertising is a bit frowned upon, but you can put a post up with maybe a bit of info (for example about toxic families) with a link to your website which allows the download. I would be open and transparent about it, and tell people when you are doing things for a commercial purpose. There are no moderators here telling you what you can and can't do, but the community will reward great content and punish spammy and/or crappy stuff.

You might want to think about what you are REALLY interested in, and go find some of those like minded people. A good place to start is the MinnowSupportProject, and some of the other really cool things that are happening in discord channels.

It can take time to make your name on Steemit. But do persevere with it, and you will quickly start to see things happening for you if you are regular and consistent with what you do.

For me, I'm part of the core #promo-steem team, and we are trying to raise the price of STEEM as well as adoption of the platform. What's happening as a result is incredible, and not something we imagined would happen so soon. This has given me incredible focus, and I encourage you to do the same.

I hope this has given you some insights. Good luck with your Steemit journey, and if you think you might be able to offer something to #promo-steem, we would love to hear from you!
