Just means there is still some gold out there available for hand register. Though I have noticed a few one-worders coming off my list in the last weeks that I didn't register.
The thing with .ws is a lot of the main words were taken and forwarded to a static marketing sell site. (You'll notice this if you search for a few minutes - most of the dropped .ws still forward to the sites.) They let some very choice names expire - probably didn't have a choice given the sheer volume - and so now just two weeks ago I registered monies.ws, etc.
I also tried to find .ws expiration pages, but besides some old expiry page I didn't see much but a smattering so I don't think much light is being exposed when some of the nice ones are dropping.
