@evan Yeah, this sort of thing seems to get lost in technical discussions comparing different social platforms.
Joining a social platform is like arriving at a party. If you are busy wondering if you are doing it right you are not going to be feeling very social, at least for the first bit. And if you didn't think to remember which door you passed through to enter the party because you are used to just entering through the front door, well, that first impression may be your only impression.
