Hey Mathias, likewise I bought HipCut a while back thinking it a catchy name for a salon chain. However, it hasn't yet yielded my early retirement. I think the truth is "hip" is becoming less common in language use.
There may be some hope as I did find the following sales at DNSalePrice.com:
Domain TLD SalePrice SaleDate SaleThru
HipEvents com $2,088 May 07 BuyDomains
HipFly com $560 Jan 07 Sedo Auction
I propose you and I team on a viral campaign to reintroduce "hip" to common language use. Are you hip?
