Lynn said: "Currently Home is not a persistent world, so when you leave Home, all of your possessions go with you. For instance, it is not currently possible for other users to visit your apartment while you're not there. We are working on the persistent aspect of Home, and expect to implement it in the long term." So this system is useless to compare achievements. You can only visit when they are online.

In its current form - yes. But Im sure they will have a global "hall of fame" or similar, where the best scores/achievements are store (for everyone). Why would anyone want to log into a system where they see a full list of everyone that has completed a particular achievement? (could be tens of thousands of names). Makes sense to do for friends. BTW - was thinking that the Wii could definitely do with a "Global Scores" Channel. You log in, and all your best scores (from VC, other games, from save games) are extracted and sent to the server - then you can see the best scores (over the world, in a country, etc).
