I usually run (if you can call it that) a contribution table called "Contrib Corner." The idea is that module maintainers and people working on projects that use Drupal (yes, even if you're doing client work or an internal implementation) have a place they can hang out.
After all, lots of projects that use Drupal result in contributions back to Drupal!
So this is the DrupalCon Global edition of that.
If you want to talk about *using* Drupal APIs, the contrib ecosystem, contributed module selection, or solving architectural challenges, come on by.
For real-time chat, let's use the #module-development channel on Drupal Slack. Link: https://drupal.slack.com/archives/C3H0RRTF0
