Yes, I did make a few sales there. But the time it took me to remove sold listings, make new logos for the new listings, then upload, just wasn't worth it. So, I decided to focus on Afternic and Dan.
As for developing starter sites for flipping, I can't really say much about that. I see myself as more of a long-haul person; whether for domains or for websites. I like fleshing things out, letting things marinate.
Building Geo domain websites isn't something I really fancy. Maybe because I don't like Geo domains unless they are pure Geos like France.com, NewYork.com or even Madagascar.com (That's me dreaming right there). Also, looking at the websites being flipped at Flippa, it's unlikely that Geo domain websites do well there.
So, if you want to go into website flipping, maybe look for other domains in your portfolio to develop.
The movie database stuff is a long term project for me and a bit personal. My idea is to get it to be an authority site for African movies down the line. No intentions of flipping. Doesn't mean I won't change my mind if a once-in-a-lifetime offer comes for the website someday.
