I am working on a site where the central page shows activity from other users nearby. (similar to a facebook or twitter newsfeed) The problem is, as this is a new site, there are often going to be zero users nearby. This will especially be true after logging in for the first time. Not a great first user experience.
We have already tweaked the meaning on "nearby," expanding to a limit if there are no close matches. This helps but we can only push this so far. We do have a call to action to invite your friends but that still can be a disappointment on first login. Right now I have "Congratulations, you are the first in your neighborhood to join. Try inviting some of your nearby friends."
I would like to know if anyone has already solved this problem elegantly. Examples in links or images would help.
