The problem with the filtering is that it isn't transparent. Updates from people I'm actually interested in don't show because Facebook's feed algorithm thinks we don't interact on the site enough, and there's no mechanism to correct it or even let me know I've missed something. Perhaps it's been fixed more recently, but I found that incredibly annoying.
