I sold all of my Hashnest stuff when the value dropped like a rock, so I haven't been following, either.
My remaining 1 GH of S3 that I was trading became unprofitable shortly after I traded it up to 2 Gh.
I also have 99% of my stuff in GHX right now. Not feeling like personal mining at the moment. My rig has been off for about a year now, and my 11 or 12 scrypt miners have been down for about as long.
They do say on the hashing page, however, that maintenance is just under 40%.
