I get the reference. Not because I get references, as a rule, but because Blackadder used it :-)

I read that as saying that they were glad he was gone, but that it didn't matter much to them - because they had moved to the self-selected "garden" of one's Facebook feed.

But I suppose I can see how that might be read as an ideal for us to be aspiring to, now that you say it. Which ... is bad, yeah. Hmm.
