I just build a new web app, and I am looking for data to seed it with. Anyone know any good seed data retailers? Or am I missing something and there is a way to do this for free. I am entirely open to scraping, and have built a couple scrapers I enjoyed.
If you're in the US or Canada infoUSA is worth checking out. A previous employer used to use them for mailings. You can be very specific with what kinds of business you want and what kind of data is required such as "must have phone number" or must be in X industry" or "must be in business over X years" etc.
Lots of sitemaps in there :)
I haven't downloaded the data and had a look at it, but it might contain usable information.
It's worth noting that people don't like their websites being scraped so they may well block you very quickly and Google is getting quite passionate about duplicate content (I can't remember the exact term for it) on different sites.
