Like I said on Twitter, it's fine until it's not. Just looking to have some sort of contingency plan in place in the case that it either collapses or changes for the worse.
I don't think it will collapse either Scott Spendolini... but if I had to switch I'd go with LinkedIn, as you mentioned it's more professional and there are already many people using it (yes, it can be very busy 😶)...
I don't think I'd go with IG or Tiktok, I don't find them so friendly for the tech community...
