My first online business, I built the site in perl iirc. Got bought out in about 2 years (that went well :) )
They eventually let the domain lapse. It got picked up by some domainers I think, it ran some crappy ads for a few years. I just looked, it got registered by a bonafide IT company in June and they've got a real site on it. Kind of odd, considering it was a contraction of two words put together and was industry specific. No idea how they came up with the same idea for a domain.
They've got one backlink. One I built :).
