I like the simplicity too and "kenoooo!" might work as an advertising jingle* so if you're the end user it's a great name. As an investment, it doesn't look so good. Resale potential appears to be low for a few reasons. Namebio shows only 4 .ooo sales: 11, 15, 700 & ig. There is no evidence of keyword.ooo demand. If a retail buyer wants a keno SLD and will not settle for a longer dot com variation, there are many keno.gtlds available (one/red/blue/black/green/college/sexy/lol/etc) to hand reg for under $10 USD. Renewal prices are a crapshoot across the board. I'd ride out year one and unload it before expiration. Good luck!
