I can see a bunch of my friends' updates on the Home page. Things like "stoot barfield finished learning Animal Kinship V". I can also see messages I posted myself, but those are more like tweets rather than "accomplishments": "Just let my daughter redesign the avatar. Might regret it."
When I acquire skills, are those automatically posted on my friends' home page / walls? If so, it'd be nice if my own skills/achievements could appear on my own wall as well.
None of this is a big deal ... I think the bigger issue is just that I'm not clear on where the updates are coming from / whether my updates are going out automatically / etc., and I'd like to have a better sense of what's going on.
