Keith Teare, founder of the RealNames navigation system that died back in 2002, tells me via email that he's regained the RealNames domain name and launched a new RealNames search engine based on the company's old data.
Teare provides more details about the relaunch on his blog. So far, it's unclear whether there are plans to bring in new data or a new business model. Teare himself notes on the blog: "To be honest, I'm not yet sure what I will do with it."
