To some extent, I think it’s important to stop and think about what your followers expect from you. I use Selective Tweets to post to Facebook because I know that’s not the same audience, and they aren’t going to see value in everything I post to Twitter, but I like being able to post to both when appropriate. Same with LinkedIn. I push blog updates to all 3, because I think most people who are following me are aware of this blog and interested in what I write here. On the flip side, I don’t push out updates from my child abuse survivor site, because the professional and personal contacts I have on those services are not the same audience as the folks who regularly read that blog, but I did create a Facebook fan page so those folks could interact with that information, and me, on Facebook if they choose to. I may not have everything exactly right for my followers, but at least I’m thinking about it and am open to suggestions.

Interestingly Jason, I did send in a feature request to ReadTwit, which pulls out items that are linked by the people you follow on twitter into an RSS feed, to allow me to filter by URL, for that exact purpose! In the mean time though, I’m filtering the folks who tweet every geolocation check-in easily enough, by not following them any longer.

The problem with pushing all of your FourSquare updates into Facebook is that the updates aren’t interesting. They probably are not even interesting to you. You so the check-in to get points or battle for mayor or earn badges. The updates make sense in FourSquare, but not in Twitter or Facebook.

The same can be said for pushing all of your Twitter updates into Facebook. The status updates in one platform often do not make sense in other platforms. All of the “RT”s and shortened URLs that make sense (or at least some sense) in Twitter make little sense in Facebook. Most likely you are not even responding in Facebook.

On the other hand, people don’t even think twice about publishing blog posts to the other platforms, or sharing interesting stories. You took the step of pushing information you found interesting. As I said above, the FourSquare updates are rarely interesting.

Add some context to the check-ins, or only send out selective check-ins from FourSquare.

Use the Selective Twitter application in Facebook. Only those Twitter updates with a “#fb” in the update will be published to your Facebook feed.

It’s a difficult one. Like many others I use twitter for mutliple purposes. I used to use two twitter accounts to separate a professional feed and local feed, but eventually it merged back into one as I was duplictaing many posts.

Personally I try to achieve a balance, I want to add some personality to my twitter feed and so add the odd post to show my interests but I also try to avoid tweeting my ever foursquare checkin. I see it a little like a law firm feed, I would rather follow a partner than a firm to catch some of the personality.

Maybe the answer is in the client rather than with twitter? Using tweetdeck etc and lists you can arrange the people. Maybe future versions will allow you to filter out urls for the likes of foursquare?
