Home still falters on the most basic level. It's just not a good social service. People for the most part don't go in there to hang out. They just go in occasionally to check out the latest spaces. They go in to look at stuff, and that's about it.
Imo, three things need to be changed to improve Home:
1. Allow you to save some spaces permanently to your HDD if you so choose, making access between areas easier.
2. Improve loading between spaces, possibly making some sort of streaming system.
3. Get game launching to work with all games, and make more spaces like the Warhawk space for other multiplayer games like Killzone.
In other words, they need to make everything more seamless, both space to space and space to game.
They also need to link your avatar to your profile, so that if you lose your data (like me) you don't have to start from scratch.
