Adding ?show=P on the end of the URL will show only people journals (no feeds or communities). You can also use filters to limit it to friends of only really interesting people (friendsfriends/filtername), though I discovered, using that method, that friendsfriends does not seem to pick up friends list entries from all my friends - if I use a small filter, it will sometimes come up blank, even though everyone on the filter had friends who had posted recently.
