has your buddy posted?

I have pretty good knowledge of PHP, however I don't think i have time to write this hack by myself, so I guessed it was better to give out the idea and maybe someone could take it.

We already have a buddy list, but I haven't found a good use for it, until I found myself searching for posts made by one of my buddy's in the last day.

We have a "view new posts" link, maybe we could have also a "view new posts by buddies" link, where we could check what and where the people in our buddy list have posted.
