Please be aware that there is some lag inherent to communicating with these services. If it is more than 24 hours, however, that is an issue. Did the change take longer than this to take place? If so, please provide your Flavors username.
I just took a look at your account, and I see a Foursquare update from 6 hours ago, and another from 20 hours ago - were they not there before?
Also, I can't see your Facebook, so I can't determine what if there's something there that ought to have been pulled in since the last update I see on Flavors from 2 weeks ago. But, just so you know, we aren't pulling in the entire contents of your wall - we're only displaying your status updates. We do have plans to have Flavors pull in more of your wall, as that is what most people expect. Anyway, if you have made status updates more recently than the last one we're showing, please let us know.
