I've been honing my scraping skills over the last few months and can now get some vast info. Some of it, I need for my projects, some of it I don't. Is there a demand for any of the following: Full sitemaps of very large websites (directories, magazines) Database of full Amazon categories Database of directory sites listings Database of regional job listings Database of Alibaba sellers (by category or region) Anything similar It's very time consuming so I don't want to start gathering info not related to my projects if it's not something I'm going to be able to shift. What's your thoughts? Worth it or not?
