To someone who has built something related to it and fully intends to run with it, yeh. I bought that domain with every intention to build something myself but am fully absorbed with something else... would love to see it put to good use, I fucking hate squatters :)
Short domain names are hard to get on account of there being fewer possible combinations. Finding a short domain that meshes with your application is definitely valuable, since it is easier to remember and type. We can debate whether or not a five letter domain counts as short, but I'd say it's valuable to someone who wants to make money. Certainly a good deal at $0.
