Show HN: ScanSpider.com – find discussions and related webpages for given url

It's tool to help find resources related to subject of your interest.

If you read some interesting article and would love to explore this subject (to write article about it or because you're just curious) you paste it to ScanSpider and it will scan Reddit and HackerNews, find discussions about it and extract webpages mentioned in these discussions to read more.

What do you think about this idea? I thought it could be great tool for journalists to collect information about given subject and context in which people are talking about it.

Do you see any other groups that could use something like this?
