I don't think this is a very good answer. If the majority of your users think that your site isn't useful (and I'm not at all sure this is the case, although I can certainly identify with this sentiment) then you need to go back to the drawing board.
Personally, I seem to have it tuned fairly well right now. By keeping a lot of people on "Important Only" updates, I don't see the memes, cat pictures, and political crap unless it's noteworthy enough to generate more than a few comments. Yet I do see the prom pictures of their kids or other things that I actually care about because they do generate enough activity to trigger whatever the threshold is to be an important post.
Either I falsley think the content I linked to is, in fact, interesting or my FB friends aren't interesting...or, perhaps, there's just a disconnect between my friends and what I think is interesting. I know otherwise intelligent people who continously post rubbish.
1) Close friends & family
2) Posts related to the subject "Programming"
3) Posts from people who haven't otherwise made it to your wall in the last 30 days.
Basically what level of granularity is currently offered in terms of FB filters, and can you setup multiple ones to switch between them?
Is this an area that FB are currently working on? Seems like this would be a good remedy for people who aren't finding the content they want.
Users are still going to be required to do some work to setup their filters though, I really don't see how you can avoid that though.
You're agreeing with the original post. That is a sign that the site is useless as is, except as an echo chamber for you to post things you are interested in but nobody else cares about.
You're posting running stuff, and there's millions of people who are interested in running stuff, but instead of those running posts finding other runners, they find your friends and family most of whom aren't interested.
That's the problem with Facebook. This is less of an issue on Twitter where it's normal for you to follow whomever you want, not just friends and family.
