KillerStartups , or rather its overarching company Startups.com Networks , has been in the news lately. First, they picked up Startups.com in a killer deal, next thing you know they're launching their own web applications ( Twingr ). Now, they're introducing the strangely named but quite useful Dataopedia , which is meant to serve as an information resource for websites. It's actually very useful, even if the idea isn't exactly new. Like you would use our own Crunchbase for information about companies, Dataopedia gives you a run-down of all the data it can find about a website you provide an URL for (including Crunchbase data, in fact). The web service aggregates data from dozens of sources in combination with a number of public APIs.
