After considering a post on names like Tumblr and Flickr, I discovered that linguistic mystic was a couple years ahead of me having posted on the use of syllabic consonants in Web 2.0 apps HERE. Money quote:
...people seem to be recognizing the syllabicity of these final consonants, and skipping the written vowels altogether when creating their site names. The flickr -r may well have started the game, but now completely unrelated sites are becoming Web 2.0 by not including the written vowel in words with syllabic endings. Pooln chose its site name over “Poolin” or “Poolen”, tumblr over “tumbler”, and I suspect it’s only a matter of time before the first sites ending in /l/ pop up (at the time of writing, rumbl, tumbl and bumbl were already reserved). Interestingly, I’m yet to see a syllabic M site (perhaps because we generally just write the m with now vowel, as in “chasm” or “orgasm”). Who knows, though, maybe “phantm” is the next Web 2.0 ghost hunting site.
