I do have FriendFeed, but I think too little people know about FriendFeed (http://friendfeed.com/johnnliu) - but it's a very techy solution. I think Windows Live's offerings will reach more people quicker.
It's already hooked to to my blog, MSN messenger
I've got 2 web activities enabled:
still waiting for a few more web activities to become enabled:
Theoretically I can just use the RSS feed from these, but I want to see what additional features I get for 'integration'.
Also, when people comment on my windows live feed, I'd like to see it in MSN messenger.
Anyway, waiting :)
