Frappr is a Web 2.0 service currently in beta that mixes the Google Maps API and social networking to see where people are on a map. The description they give is:

Frappr (Friend Mapper) lets you see the zip code where your friends live or work, letting you find out who works in the office building next door and who lives in the apartment complex across the street.

In my opinion, a better name for the service would have been Frapper. Flickr seems to have set a Web 2.0 naming convention of leaving out the 'e' before the 'r'. I'm sure flicker.com exploded in typo traffic when Flickr rose to prominence, and if Frappr goes anywhere, Frapper.com will definitely do the same thing.

Their logo also needs some work. It currently looks like a kindergarten art project, and the slanted 'r' at the end doesn't make it any better.

Their Alexa traffic graph is quite interesting...

The best description for it, would be that it resembles a rocket being shot up and then gliding back down to the ground, occasionally lifted by a gentle breeze. What could have caused such an enormous explosion of traffic, from 0 to 600 per million in a month or two? Their Wikipedia article states that

Frappr's meteoric rise in the fall of 2005 was due to Frappr's easy single click interface and its numerous widgets allowing users to utilize Frappr's maps on their own webpages. [...] Frappr was originally hosted on www.risingconcepts.com and entering this domain into Alexa will show the sharp spike in traffic the site incurred when Frappr caught on in popularity. This explains the immediate spike in traffic for the domain name frappr.com after the switch in domain names was made.

It's ironic that the company behind the service is named Rising Concepts, since traffic seems to be falling quite rapidly.

The service itself seems quite interesting. Everything mentioned so far has been relatively superficial, and I think the service still stands a chance, given its existing popularity. It would be advisable for them to work a little on their logo and website design.
