Value of dot-coms falling
"That's 55 percent: a high figure, and could well point to the fact that the value of dot-coms is falling."
Not at all surprised that the value of dotcoms is still falling, and that's even since the dotcom bubble of the 90s. The
cybersquatters domain investors have only themselves to blame: people learned many years ago that searching for stuff on the internet by typing "<subject I'm interested in>.com" into the browser address bar was the worst possible way to do it, simply because such efforts invariably led to a parking page devoid of anything useful, offering the domain for sale - or more likely, some spammer's malware-ridden link farm.
These days, few people remember what or where the address bar even is; most people now simply type what they want into Google* and click the result links - or they follow links posted by their friends on Facebook. Consequently, the domain name is no longer as relevant as it used to be, and these days it doesn't matter if your company has to use something like thisisaverylongdomainnametotypeintoyourbrowseraddressbar.com, since the major driver of traffic now is search engine rank and social media referrals, not so much "accidental drive-by" traffic.
These days, you don't tell people to "point their browser" to your domain, you just tell them to "find us on Facebook" and link them to your site from there.
*How many times have you given someone a domain name only to see them type it into the search box instead of the address bar and then click the search result from there?
