eldavojohn notes that Groklaw is highlighting the
unexpected Wolfram|Alpha ToS — unexpected, that is, for those of us accustomed to Google's "just don't use it to break the law, please" terms. Nothing wrong with Wolfram setting any terms they like, of course. Just be aware.
"We've seen people comparing Wolfram's Alpha to Google's Search from a technical standpoint but Groklaw outlined the legal differences in a post yesterday. Wolfram|Alpha's terms of use are completely different in that it is not a search engine; it's a computational service. The legalese says that they claim copyright on the each results page and require attribution. So for you academics out there, be careful. Groklaw notes this is interesting considering some of its results quote 2001: A Space Odyssey or Douglas Adams. Claiming copyright on that material may be a bold move. There's more: if you build a service that uses their service or deep-links to it, you may be facilitating your users to break their terms of use, and you may be held liable."
