Recently, we have seen a spate of cross-posted questions on ELL and EL&U (such as this one on EL&U).
I can understand the frustration of a new user looking for an immediate answer to their question, but as we all know it does not work that way here. Posting on either site requires a certain patience, yet many newbies seem to have to have such an urgent problem which, if not answered in the first hour, well... they go off looking for alternatives. And sometimes that comes back to the english.SE in 2 or 3 hours.
We are possibly a little unique on SE: we have a split personality. Usually, most new users come here first, and are only directed to ELL when it is obvious that their issue is too basic for EL&U.
On the other hand, sometimes new users post on ELL first, and when they do not get an immediate response they start banging away at the keyboard in desperation, looking for an answer. For most internet surfers, that's the way things usually work and they end up here on the main.
There are some opinions on the topic of cross-posting, most notably from Jeff Atwood
Allowing cross-posting is a slippery slope.
If you might have slightly better odds of getting an answer by posting it on two sites, well, by gum, why not maximize your odds by posting it on twenty sites!
There are some questions which fall into grey areas between sites, and I think it's OK to ask and delete, then re-ask if you feel you have asked on the wrong site.
But as a general rule, do not cross-post questions, please. Pick a site and go with it.
On this site, cross-posting is more than discouraged: it seems to be a reason for closing. [Sorry cannot post a screen shot of the close reasons as they get deleted on close]
After a number of exchanges of comments on the topic (Jason Bassford, Janus Bahs Jacquet,and others) I found this to be more pertinent from Mary-Lou A:
@Cascabel the thing is, the same question could be posted if the OP hasn't received any answers on the older post but they shouldn't hide this information AND they should wait at least two days before cross posting.
Some users are active on both sites; and they seem to be most aware of the situation.
My question is:
If a question is cross-posted on the same day on both sites, Which gets closed first? The first with no answers, the one most apt for the site...and who makes that judgement? Not everyone participates on both sites, so it seems that on EL&U we are closing based on the cross-post in ELL... but is that the best approach?
[BTW] Most users are probably not aware of it, but ELL users CANNOT vote to migrate to EL&U.
