In another thread I brought up the issue of the Flippa API and am awaiting a reply from Andrew (from Flippa).
In the meanwhile I'd appreciate your suggestions for what data you'd find useful. For example, I could track
1. For each site listed .... whether it came up for sale in the past ....and provide data from those previous listings
2. For sites that have sold, whether their WHOIS details got changed over (so several months later if the WHOIS hasn't changed it could be worth approaching the seller)
3. Sellers and their claimed connections - a nice connections map perhaps?
I don't know what data Flippa provides and, of course, whether they'd allow access to their API . But what information would you like to see extracted?
