Welcome, @amandaclarke. Not part of the Adelaide or Australian contingent, but I thought I'd say hi, anyway. Personally, being shy, introverted, or reserved seems to be par for the course here, and the opportunity for all of us who fall into any or all of those categories to express ourselves without having all the people who will read what we've said staring at us while it's happening. :)

Good luck with your endeavors here. Matt and I have conversed a time or two, and he definitely knows how to navigate the waters so no doubt you will find your niche and enjoy your time on STEEM.
