GeoChirp helps you search for people twittering for specific things in a specific area. It has very simple and interactive interface. Since it depends on the “location” information of twitter – which is not always accurate or not empty, the results are always correct. But still gives good and unexpected results.
Pros & Cons
|Uses OAuth for twitter login||Does not always provide many results due to incorrect supplied locations by twitter users|
|Ability to increase area of the search up to 50 miles in radius|
|Interactive (ajax) simple interface|
|Can make the search as universal|
