Most of us were always busy for web2 posting... Probably, it's time to try to carve some time... Simple posting of what you already have (better within a certain niche) is a good start, with captions/thoughts that give the slightest chance for a discussion - no need to be the biggest joker on Threads if you don't feel this way.
Secondly, if some of us will like blogging on Threads and - one day, eventually, in a year or so - reach like 5000+ subscribers with active engagement, it's already the level when companies (like photo equipment ones in case of photographers) can become interested in you as a micro-influencer.
So.... Joining this initiative is investing in your own influence online, developing your own web asset, a Threads blog, with the support of HivePosh. Sounds cool to me.
