One letter domains has the same issue as many of the gTLDs, they aren't particularly useful in terms of brand recognition. X.com is pretty stupid as well, you can't meaningfully use it as a brand. Take bob.builders, it's a perfectly valid domain, but if you see it on the back of a van, even if it's www.bob.builders, it's not recognizably as a website. www.b.com has the exact same problem, even x.com / www.x.com is ju…
> X.com is pretty stupid as well, you can't meaningfully use it as a brand. Just "x" alone isn't really the brand. It's more like "x.com" is the canonical name.
