If you are buying 4N, 5N and 6N dot coms, you’ll most likely find the Sedo auctions which are ending today (approximately 4 hours and 45 minutes left at the moment of writing) interesting.
Short domains have without a doubt contributed to a bit of a “rebirth” of Sedo, a company which wasn’t exactly on the right track when it comes to the reseller market at least (in my opinion) prior to the short domain phenomenon.
