Speaking of dropping vowels, Flickr dropped its “e” for less stylistic reasons. When the founders of Flickr went to buy the domain name “flicker.com,” they found it was already taken, and the owner wasn’t interested in selling. A team member suggested they drop the “e,” and the name stuck. In fact, the missing vowel may have actually led to increased interest, according to co-founder Stewart Butterfield.
"We always had to spell it out for people, which helped make it stick," he told CBS.
In the end, Flickr had the last laugh. According to TechCrunch, Yahoo (which now owns Flickr) bought the domain name Flicker.com in 2010, which was reportedly receiving more than 3.6 million visitors per month (likely due to Flickr misspellings).
