Maybe I’m misunderstanding, but usually what “X diaspora” means is “people who have been X but have now moved elsewhere”.
Or have ancestors from X.
I would probably consider a regular SSC commenter to be part of the LW diaspora even if they have never personally been a regular LW commenter. (Not so sure about InIn, as AFAICT Gleb Tsipursky hadn’t been a LW regular before founding it.)
If what you want to know is “what characteristics do LW participants and ex-participants have” then you want to survey LW participants and ex-participants, and responses from other people will not help to answer that question. And if their survey answers don’t clearly distinguish the other people from the participants and ex-participants, they will make the answers less useful. I forget how clearly the questions ought to make it possible to distinguish, but given that people make mistakes and don’t fill everything in I suspect that in practice they distinguish much less than perfectly.

I don’t think that’s true. Having a control group quite often does help you to know more.
With whom? My understanding is that this is intended to be a survey of people who either are or have been LW participants.
This is a diaspora survey, for the pan-rationalist community.
Hence “have been”. Maybe I’m misunderstanding, but usually what “X diaspora” means is “people who have been X but have now moved elsewhere”.

Having more data is good regardles of the semantics.
Not if the “data” is noise.
Most of those who haven’t ever been on Less Wrong will provide data for that distinction. It isn’t noise.
