Definitely Halloween; 'boo' names are getting a lot of interest. Don't know about any being actually sold by resellers for coin of any mention, but a lot of people are reg'ing them, so won't hurt to sit on it for a year or 3 with it parked for sale.
Since Halloween is big bi'ness, at least for a short spike in the year, might be nice to start a simple site for anything related.
At the moment, I wouldn't give the name value to reseller; maybe a few xx to an end user if they like it, undeveloped.
But like I said, perfectly all right to hang on to Boo names for awhile to see if there's a light at the end of the tunnel for all these boo regs.
