Love the concept and look of it however I know companies before had issues integrating listings from craigslist because of their terms of service. Has this changed at all? If not it may be something to watch out for...read what happened to oodle: http://www.siliconvalleywatcher.com/mt/archives/2005/10/crai...
Yeah, from what I know it's been a problem. I think because of this we will release it as a free application to start off on and see how things go.
Time can only time I guess?
Just be careful, don't want to waste your time banking on something that is your only business model should it get taken away. Otherwise the app looks great and very useful!
