As you probably know it sold previously for $5k. As you say a 3 letter short word has value, and sly and net could make sense for various possible uses. I can see a slight increase from previous price, although it is hard to get that high a price even for short .net lately. If I look at LLL .net sales from last 2 years on NB wet went for $7.8k and app went for $70k. Yea went for $5k. I see something high $$$$ as the likely price, but might ask a bit more to start so room to negotiate.
