How is 4sq worth millions but yelp is worth billions? I find them both to be very similar services. Should there really be that much of a difference in valuation between the two? Seems like one is either over-valued or under-valued.

4sq has struggled mightily with traction/retention since the big change. Yelp is ubiquitous in the US and they are making strides into other countries.

Yelp had sales of $377m and profits of $36m which while not huge are at least profits. Foursquare is presumably losing money if it raised $45m in a down round.

Because when you google most small businesses, yelp shows up on the first page. Other than downloading the app, I don't know how you'd find 4sq info.
