Those kind of domains don't really have any value because of their extension and also they are not CEO friendly like .com , .co , .NET , .ORG etc. ..
I never trust any website with an unusual extension, I only trust websites with the well known .com , .co , .NET, etc extensions. If a domain is too long I view it as suspicious too. Most people probably don't trust unusual domains so you can buy them cheaper, but get less page views if you use them.
is my domain too long??? Its to the left.
