I was just speaking to someone today that wants to dispose of their site/domain.
They have just let the domain sit there, online, for the last four years as it has been relatively cheap to host and renew the domain.
They told me they cannot make a go of the business as they were too busy with other matters.
I guess that's what happens.
Post Panda, it's quite likely many more domains and sites will remain in that same state of limbo, although this particular site didn't rely on advertising income of any kind.
Well done on acquiring yuor domain for a snip!
