I use HN comments as my blog. My only advice would be to write naturally without any self-consciousness, forcing yourself into some style etc. Only think about the content you want to convey and let the "how" flow naturally. I read a lot (varied subjects) and through that process have somehow internalized some aspects from various styles which when expressed in writing becomes "my own style".
Reading is a prerequisite for Writing, and so browse/skim/read/study a lot. Then trust your inner self/intuition to do its thing by freely expressing itself in Writing.
To get some background on this sort of mindset, you might find the book The Unfettered Mind: Writings from a Zen Master to a Master Swordsman by Takuan Soho and translated by William Scott Wilson helpful (see https://en.wikipedia.org/wiki/The_Unfettered_Mind). The book is written w.r.t. Martial Arts but the principles/mindset enunciated therein are applicable to any endeavour.
