Often, a simple answer is the best answer in software engineering. Take for example the quandry of multiple city craigslist searching ( or multi-city search ). Craigslist, being the localized tool that it is, does not allow searching multiple cities, locales, or really even categories.
Many folks have tried to put together websites that perform multiple city searches. One of the best was developed by Steve Atwood of Coding Horror. Like most others, his was shut down by a friendly letter from Craigslist. Others have cobbled together odd-looking multi-frame solutions that seem no better than opening several tabs in Firefox.
Directly utilizing search engine indexes in a very straight-forward manner enables craigfind.com to legally search multiple cities, multiple categories, and even use regular expressions. Pretty much anything you would expect from a Google search is available.
This is an example of a very simple solution to a sticky problem, utilizing existing technology in, frankly, a rather non-innovative way. Amazing thing, this internet.
