At dinner tonight, some of my friends were threatening to drop me on one "or more" social networks due to excessive crossposting. This confused me.

I've just verified my settings and double checked my archive page, and I still don't get this claim.

Here's my current setup (largely because I despise Facebook and try to avoid interacting directly with the damn thing):
public Livejournal posts -> Facebook notes
tweets -> Facebook status updates
Google Reader shared articles -> Facebook (although my comments are stripped off)

There's also some stuff on tumblr and friendfeed, but I don't think anybody is significantly using those platforms.

If you are following me on one of those three "real" services and following me on Facebook then you will see duplication. If you see any more duplication than that, let me know.
