Unless the platforms themselves are filtering, everything shows up everywhere anyway and if it's not mentioned somewhere (with the app self-signing somewhere for example) then none of us are going to know what you posted with ;D
You can do it! Just keep steeming and steeming well XD
Yes, this is true @ryivhnn, good point. I just feel somehow wrong or bad when creating a little short "Tweet-like" post like that on SteemPeak, which is meant to be a "blogging" platform. All of my Zaps on #Zappl automatically get a timestamp and the word "ZAP" in the title, to denote that they are from Zappl, but you're right, SteemIt and SteemPeak don't actually filter them. Zappl itself filters everything other than its own entries on the blockchain.
Thanks for the upvote. It all helps. Although at this stage I don't think I'm going to make the "50 Reputation within 100 Days" goal that I've set for myself. I'll be close to it, I'd say, but not quite actually inside of the 100 days. It's all good though, and I really appreciate all the support that I've received, getting to where I am. It's amazing! 😃
