My team didn't socialize before this and aren't socializing now either. In the office we didn't even sit together! We saw eachother at standups for 15-30 mins and then whenever we needed to work together.
Now it's a conferencing call for the 15-30 mins during the day and people can contact whoever they need to work with.
I'm not even sure how socializing in a conference call works. Aren't people speaking over each other and won't it just end up with the biggest talkers taking over? Not that that is too dissimilar to face-to-face interactions..
