In my relatively recent experience - aka 'Xiphware' - it can be surprisingly difficult, now, to find something suitable that is still available; not just the domain name but all the readily associated Facebook, Twitter, etc handles. I found this was useful: https://www.namecheckr.com/
Certainly something incredibly obscure (ala 'Enketo') helps...
[I note, "odenkobo" is still fully unclaimed, remarkably... lol]
