Edgeio launched last week – a service that crawls real estate web sites and blogs to aggregate listings.
It was founded by RealNames founder Keith Teare and TechCrunch blogger Mike Arrington. The site uses RSS and XML to collect content from various web sites based on tags and then displays them online.
The process is fairly simple. You tag your listings with keywords and Edgeio will index them along with other keywords.
The concept is interesting, although the future for “content aggregators” like this is in question. The market is only so large for companies who rely entirely on content from other people, although this is essentially what Google, Yahoo and the search engine companies do.
