Hello Eugenie and welcome to this planet!
Your brief more social introduction was a step in the right direction. It is true what @thauerbyi said - it's a tough call making yourself visible at first. Your experience in the ad-world is likely to help making the essence of what you wish to share most salient.
My intro as an introverted old hermit was way too serious..washed into oblivion by a solid stream of garbage, barely noticed. And I suspect, over and above this, that there is a slight bias amongst the more salted inhabitants against any newbie making a serious statement, with a hard to turn cognitive dissonance kicking in!
All the best!
ps..as a fellow inhabitant of this beautiful country, should you ever wish to visit Stilbaai, 'somerlus' in your search engine will lead you to reservations for a cottage right on the beach ;)
Be still my heart! Somerlus sounds sublime. And I have serious wanderlust right now... So who knows ;)
