Tumblr, Flickr, Grindr, and Plntr are vowel-drop names. The pattern was peak-popular in 2008 to 2014 and has cooled since then because pronunciation friction is now a real cost in voice search and AI assistants. Modern usage tends to drop fewer vowels (Glossr, not Glssr) to keep the name pronounceable. Vowel drop is most useful when the un-dropped form is taken and you can defend the spelling with strong marketing.
