Page should tell at first glance what gitter DOES.
Looks like HN announced it for us...
Just leave them on. We get the message.
I opened an issue about having a description of the project in the landing page: https://gitlab.com/gitlab-org/gitter/webapp/issues/1746
There's also https://gitlab.com/gitlab-org/gitlab-ce/issues/32794 which always shows you where you are (within GitLab), which is tangentially related
