Here are some examples of sentences that could have been better:

• "It’s important to be clear with the intention behind this project from the start and share my reasoning and ideas behind creating this platform." Two issues here. First, it badly needs a comma before "and." Also, I would write "clear about," not "clear with."

• "The solutions to these problems should be the guide to creating this platform." This is just a clunky sentence. How about: "The solutions to these problems should serve as a guide in creating this platform."?

• "If the problems aren’t worth solving then perhaps the platform is not worth creating?" Comma before "then." Or even instead of "then."

• "I believe If the Steem network wants to grow it needs to be a more integral part of a creators platform." A few issues. "I believe that if" work better. There should be a comma before "it." "Creators" should be "creators'"

These are just examples. The biggest takeaway is that if you would make a short pause while saying a sentence, you should probably put a comma there when you write it.
