Methinks peppy's !announce wouldn't work if #osu weren't open. :v
Anyway, what's the big deal? You can have other tabs open, osu! remembers the last active channel upon logout (so you don't even have to SEE #osu when you login again), and if you don't want to see chat in the first place, then you can just not hit f8.
Also, think of all the newbies that will accidentally close the channel and not be able to use their brain to open it again. *imagines Help forum spam as usual* "halp i cant tie my own shoes ): ): ):"
