Perhaps it would be wise to open #Ubuntu-LTS?

Thank you for your verbose replies :)

I don't think Dapper is relevant. I think this channel should focus on
the desktop only, because there is much less traffic in #ubuntu-server
and the percentage of LTS server installations are much higher. The
desktop also changes more when you consider that most desktop users
will primarily use the GUI.
