I suppose like all businesses it is on sale for the right price, but I haven't given much thought to actively attempting to sell it beyond "I don't think the standard going rates for small Internet businesses would value this highly enough to make me want the lump-sum of money more than I like owning it."
I don't believe that to be true. BCC is very close to running itself at present. Selling BCC would mean a lot of effort to make a clean break from it -- for example, my bookkeeping system is inextricably entangled it it at present ("It sounded like a great idea in 2008!"), so I'd need to rip that out, set up a new bookkeeping system, teach my VA how to work that, sanitize the DB backups, etc. Also, selling it is likely to be a protracted process -- there would need to be contracts/escrow/technical assistance/etc.
There is, of course, a nuclear option to shut down transactions, EOL the product, and shut down any support other than FAQ/T1/"Here's how to request a refund check." That's probably less work to set up than selling it.
