People thought it was going to be like the AOL keywords of yore - but it was already so late in the game that nobody gives a shit, you either use google to search for bing or you just don't care.

There's probably ten or twenty domains (not counting my own or my work's) that I can type from memory, the rest I just search for.

The other killer is that "clownfarts.com" looks like a website but www.mcdonalds looks like a typo, even to non-tech people who don't understand any TLD besides the big three.
